Question

Evaluate the function f(x) = 3x + 5 for each of the following input values:
a. Find f(0)

b. Find f(4)

Answer 1

To find the output, we simply plug in the input values into our x-values.

For a) we will input 0 where x is. 3(0)+5= 5. So the answer for A) is 5.

For b) we will input 4 where x is. 3(4)+5= 17. So the answer for B) is 17.
