Question

given the function f describe by f(x)=2x find each of the following
a. f(-7)
b. f(6)
c. f(29)

Answer 1

just sub in

Answer 2

for the first one, where you see an x, replace with a -7

Answer 3

a. = 2(-7) =-14

Answer 4

the others are exactly the same, just bigger numbers

Answer 5

it could even ask something like f(x) = 2x

find f ( x+h ).

This is exactly like the other questions, whereever you see an "x" in a function you should replace it with a (x+h)

so in that case f(x+h) = 2(x+h)

Answer 6

I'm confuse

Answer 7

Answer 8

Answer 9

Answer 10
