Question

F(x) = 6x - 8 when x = 4

Answer 1

Answer:f(4)=16

Explanation:

all we have to do is plug 4 for x

f(4)= 6(4)-8

that means 6*4 is 24

f(4)=24-8

f(4)=16

Answer 2

f(x)=16

Explanation:

Substitute 4 for x. Then, multiply. 6x4=24. Then subtract...24-8=16.

f(x)= 6x4-8

f(x)= 24-8

f(x)= 16
