What is quadratic equation of graph?A quadratic function is one of the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola.
The vertex form of a quadratic function is f(x) = a(x - h)² + k, where (h, k) is the vertex of the parabola. The coefficient a determines whether the graph of a quadratic function will open upwards or downwards.
Here, vertex is (h, k)=(0, 0) and coordinate point is (x, y)=(-2, 5)
So, 5=a(-2-0)²+0
5=4a
a=5/4
Substitute, a=5/4 and (h, k)=(0, 0) in vertex form we get
f(x)= 5/4 x²
Equation of straight line with coordinates (-2, 5) and (0, 0) is
Slope m=5/2
Substitute, m=5/2 and (x, y)=(0, 0) in y=mx+c we get
0=5/2(0)+c
c=0
Substitute, m=5/2 and c=0 in y=mx+c we get
y=5/2 x
So, g(x)=5/2 x
Now, h(x)=f(x)-g(x)
h(x)=5/4 x² - 5/2 x
h(x)=5/2 x(1/2 x-1)
1) h(x)=0
5/2 x(1/2 x-1) =0
1/2 x-1=0
1/2 x=1
x=2
2) For x=2, h(x) is 0
3) Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Therefore, the function h(x) is h(x)=5/4 x² - 5/2 x.

Whats the absolute value of 5/6?
Answers
Answer:
the absolute value of 5/6 is 5/6
Step-by-step explanation:
absolute value is just the distance from zero on a number line, so it just makes whatever number under the | x | the same number but positive.
Answer:
5/6 is the same you dont change it unless its negative
Step-by-step explanation:
If the fraction is positive, it is its own absolute value. If the fraction is negative, remove the negative sign. That is the absolute value. In other words, the absolute value of 1/7 is 1/7, and the absolute value of -5/8 is 5/8.

A gift basket has 2 soaps and 5 lotions and costs $20. A second basket has 6 spas and 15 lotions and cost $60. Is it possible to determine the price of the soap?
Answers
A second basket has 6 spas--- I think you mean 6 soaps , so i will work with that
Answer:it is not possible to determine the price of the soap with the information given.
Step-by-step explanation:
Let s0ap be represented as x
and lotion be represented as y
2 soaps and 5 lotions costing $20 gives us equation 1 as
2 x+ 5y= 20-------- equation 1
second basket with 6 soaps and 15 lotions and costing $60 gives us equation 2 as
6x + 15y= 60------equation 2
Step 2 -- Solving
2 x+ 5y= 20-------- equation 1
6x + 15y= 60--------equation 2
BY elimination method, we multiply equation 1 by (3)
2x + 5y= 20 x (3)
6x + 15y=60-------equation 3
Subtraction of equation 3 from equation 2 gives us
6x + 15y=60-------equation 3
-6x + 15y= 60--------equation 2
0x +0y=0 which is no solution
Therefore it is not possible to determine the price of the soap
