Question

For the given function f(x)=2x+4,find f(12)

Answer 1

f(12)=28

Explanation:

We want to find what y or f(x) is when x equals 12

To find f(12), substitute 12 in for x

f(x)=2x+4

f(12)=2(12)+4

Multiply

f(12)=24+4

Add

f(12)=28

Answer 2

f(12) = 28

Explanation:

All you have to do is plug in 12 as x.

f(12) = 2(12) + 4

= 24 +4

= 28

And you're done! :)
