Question

If f(x)=x^3+6x-8,t=z+2 find f(t)​

Answer 1

Answer:

If f(x) = x2 – 5 for all values x and f(a) = 4, what is one possible value of a?

Possible Answers:

8

1

3

14

11

Correct answer:

3

Explanation:

Using the defined function, f(a) will produce the same result when substituted for x:

f(a) = a2 – 5

Setting this equal to 4, you can solve for a:

a2 – 5 = 4

a2 = 9

a = –3 or 3
