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

f(12)=28

Step-by-step 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: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
