Question

What is the value of f(5)

what is the value of f(10)
what is the value of f(0)
what is the value of f(-2)

Answer 1

243, 0, 20, and I don’t know the last one, I’m sorry

Answer 2

a. 20
b. 35
c. 5
d. -1

Explanation:

Given f(x) = 3x+5, you want to know the values of f(x) for x in {5, 10, 0, -2}.

Evaluate

To evaluate the function for the given values of x, put each in place of x and do the arithmetic.

f(5) = 3(5) +5 = 20

f(10) = 3(10) +5 = 35

f(0) = 3(0) +5 = 5

f(-2) = 3(-2) +5 = -1
