For the function ƒ, c is a constant and ƒ(3) = 12. what is the value of f(−3) ? ƒ(x) = cx2 + 30 a) −12 b) −2 c) 0 d) 12

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.
