Question

1. What is the value of f(4) in the function f(x) = 3x - 7?

a) 5
b) 8
c) 1
d) 9

2. In the function f(x) = 3x - 7, what value of x makes f(x) equal to 20?
a) 9
b) 10
c) 7
d) 8

Answer 1

The value of f(4) in the function f(x) = 3x - 7 is 5.

Step-by-step explanation:

To find the value of f(4) in the function f(x) = 3x - 7, we substitute x = 4 into the function:

f(4) = 3(4) - 7

f(4) = 12 - 7

f(4) = 5

Therefore, the value of f(4) is 5.
