Question

If f(x)=3x+10, find f(4)?

a. f(4)=17
b. f(4)=22
c. 22
d. f(4)=12

Answer 1

`f(4 )= 22`

Explanation:

`f(x) = 3x + 10`

`f(4) = 3(4) + 10`

`f(4) = 3 * 4 + 10`

`f(4) = 12 + 10`

`f(4 )= 22`

Hope it is helpful...

Answer 2

f(4) =22

Explanation:

f(x)=3x+10

Let x=4

f(4)=3*4+10

Multiply

f(4) =12+10

Add

f(4) =22
