the graph of y=f(x) is shown below. what are all of the real solutions of f(x)=0
Answers
All real solutions of the function y=f(x) are x = -4 and x = 4
What is a solution ?Suppose that we've a function y = f(x) such that f(x) is quadratic.
When y = 0, then the values of x for which f(x) = 0 is called solution of quadratic equation f(x) = 0. These solution gives values of x, and when we plot x and f(x), we'd see that the graph intersects the x-axis at its solution points.
we are Given graph in the attachment represents the function y = f(x)
Since Real solutions of the function shows all the points where the curve of the graph either touches or crosses the x-axis.
Thus the graph of the function touches and crosses at x = -4 and x = 4
Therefore, all real solutions of the function y=f(x) are x = -4 and x = 4

Question If Jim has 60 spoons and Jim has a friend named Jim that has 157 and has another friend named Jim with 537 spoons and pooled all their spoons together and Jim 1 took the spoons to a blacksmith to make small spoons by breaking the spoons to thirds and 27 spoons broke, Jim 1 had the blacksmith make a normal spoon from the remains which makes 3 normal spoons how many spoons do all the Jims have together and how many spoons do each Jim have individvally? I just thought of this on the spot so i dont know the answer anywho I need an answer cause i wanted to ask this to my friends and say the answer to seem smart lol
Answers
Step-by-step explanation:
Jim 1= 60 spoons
Jim 2= 157 spoons
Jim 3= 537 spoons
after Jim 1 took the spoons to the blacksmith he broke 27 spoons which means
Jim 1= 60-27 which leaves him with 33 spoons.
and now
Jim 1= 33 spoons
Jim 2= 157 spoons
Jim 3= 537 spoons
3 normal spoons outta 33 spoons which means he used 11 spoons per each spoon
and now
Jim 1= 3 spoons
Jim 2= 157 spoons
Jim 3= 537 spoons
so finally, all the Jims have 697 spoons in total.
a bit tuff...lol

Step-by-step explanation:
Coordinates of Points
A point is the basic relationship displayed on a graph. Each point is defined by a pair of numbers containing two coordinates.
A coordinate is one of a set of numbers used to identify the location of a point on a graph.
Identifying the x-coordinate
The x-coordinate of a point is the value that tells you how far from the origin the point is on the horizontal, or x-axis. To find the x-coordinate of a point on a graph:
- Draw a straight line from the point directly to the x-axis.
- The number where the line hits the x-axis is the value of the x-coordinate.
Identifying the y-coordinate
Now that you know how to find the x-coordinate of a point, you have to be able to find the y-coordinate.
The y-coordinate of a point is the value that tells you how far from the origin the point is on the vertical, or y-axis. To find the y-coordinate of a point on a graph:
- Draw a straight line from the point directly to the y-axis.
- The number where the line hits the axis is the value of the y-coordinate.
Notation for Identifying Points
Once you have the coordinates of a point you can use the ordered pair notation for labeling points. The notation is simple. Points are identified by stating their coordinates in the form of (x, y). Note that the x-coordinate always comes first.
