If f(x)= 2x then f ^-1(x)=

a. -2x
b. 1/2x
c. x-2

You are supposed to simplify (2+h)^{2}-2*(2+h)

1/2x

Step-by-step explanation:

f(x)=2x. This means that f=2 (since x=x)

2^-1= 1 divided by 2. 1/2= 0.5.

0.5(x)=1/2x.

the answer is 8

step-by-step explanation:

3.14 x 8x8

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
