Question

Suppose that the function f is defined, for all real numbers, as follows.

Find f−4, f−2, and f2.

Answer 1

f(-4) = -4/3

f(-2) = -2

f(2) = 8/3

Explanation:

we need to use equivalent functions to get the answer. we use the equation which satisfies the function.

f(-4) we use the first function

f(-4) = -1/3(-4)² + 4

= -4/3

f(-2) = -2 . we have used the second function

f(2) = -1/3(2)² + 4

= 8/3. we have used first function
