Answer:
D. 12
Step-by-step explanation:
We have been given a function , where c is a constant and f(3)= 12.
To find f(-3) we will find value of c by substituting value of f(3) in our given function.
Upon substituting value of c in our given function we will get our function as
Now let us find f(-3) by substituting x=-3 in our function.
Therefore, f(-3) is 12 and option D is the correct choice.

Answer:
(2, 7)
Step-by-step explanation:
represents the reflection of a point P about the y-axis.
If a point (x, y) is reflected across y-axis, rule for the reflection is,
(x, y) → (-x, y)
If a point (-2, 7) follows the same rule, coordinates of the image point will be,
P(-2, 7) → P'(2, 7)
Therefore, answer is (2, 7).
Answer:
(2,-17) should be the minimum.
Step-by-step explanation:
The minimum of a quadratic function occurs at . If a is positive, the minimum value of the function is
occurs at
Find the value of
x = 2
evaluate f(2).
replace the variable x with 2 in the expression.
simplify the result.
The final answer is -17
Use the x and y values to find where the minimum occurs.
