Question

Find the value of fx) = 3x + 7 for x = 8.

Answer 1

the value of f(8) is 31

Explanation:

To find the value of f(x) = 3x + 7 for x = 8, we need to substitute 8 in for x in the equation and perform the arithmetic.

f(x) = 3x + 7

f(8) = 3(8) + 7

f(8) = 24 + 7

f(8) = 31

Answer 2

`f(x)=3x+7` x = 8

Substitute 8 with x:

`f(8)=3(8)+7`

`f(8)=24+7`

`\fbox{f(8) = 31}`
