If f(x)=X²-3, what is the value of f(-3)?
__________________________________________________________
Hello! In this question, we are trying to solve the expression with a given value.
__________________________________________________________
Explanation:
In this question, we were given our f(x) equation: f(x) = x² - 3
We were also given the value of our variable "x": -3
To solve the expression, we would plug in our "x" value, -3, into the "x" variables in our expression and solve.
Solve:
f(x) = x² - 3
f(-3) = (-3)² - 3
= 9 - 3
= 6
Therefore, the value of f(-3) is 6.
__________________________________________________________
Answer:
f(-3) = 6
__________________________________________________________
To solve this problem, you will substitute an existing value into a function in order to find the y-coordinate at that x-coordinate.
SubstituteGiven the function f(x) = x² - 3, evaluate the function at f(-3) by substituting in x = -3:
[tex]f(-3) = -3^2-3[/tex]
Use Order of OperationsUse BPEMDAS, which stands for:
Brackets
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
First, evaluate -3².
[tex]-3\times-3=9[/tex]
Then, evaluate the rest of the expression by subtracting 3 from 9:
[tex]9 - 3 = \boxed{6}[/tex]
The final answer is f(-3) = 6.
What is the quotient of (x3 6x2 11x 6) ÷ (x2 4x 3)? x 2 x – 2 x 10 x 6
The quotient of [tex](x^3 + 6x^2 + 11x + 6) \div (x^2 + 4x + 3)[/tex] is x + 2
How to determine the quotient?The quotient expression is given as:
[tex](x^3 + 6x^2 + 11x + 6) \div (x^2 + 4x + 3)[/tex]
Expand both expressions
[tex](x + 3)(x + 2)(x +1) \div (x + 3)(x +1)[/tex]
Cancel out the common factors
x + 2
Hence, the quotient of [tex](x^3 + 6x^2 + 11x + 6) \div (x^2 + 4x + 3)[/tex] is x + 2

Answer:
The length of the wing is 480 centimeters
Step-by-step explanation:
2 cm on the drawing is 192 cm on the acutal wing
2 = 192
divide both sides by 2
1 = 96
since the drawing has a length of five cm, multiply both sides by 5
5 = 480
therefore, 5 cm on the drawing is equal to 480 cm on the actual wing

Answer:
well I think it is so because it has to do with affecting the positive sign just think of it using normal circumstances
Step-by-step explanation:
formally, there is only one alternative : if not negative, it would be a positive number.
and that would mean
2× -4/5 = x (= a positive number)
2× -4 = 5x (= still a positive number)
-4 = 5x/2 (= still a positive number)
and -4 is definitely not a positive number.
so, it is proven, 2× -4/5 cannot be a positive number, and therefore has to be a negative number.

Part B: Write one function for each car to describe the value of the car f(x), in dollars, after x years.
Part C: Baxter wants to purchase a car that would have the greatest value in 10 years. Will there be any significant difference in the value of either car after 10 years? Explain your answer, and show the value of each car after 10 years.
Car 1: It is an exponential function that is given as P = 18,500 (0.9595)ⁿ and the price after 10 years is $12,235.5.
