Find f(2) if f(x)=(x+1)^2
a. 9
b. 6
c. 5

a. 9

Step-by-step explanation:

If f is at 2, then you subsitute anywhere that an x is with a 2. So in this particular equation we get

f(2) = (2+1)^2

f(2) = (3)^2

f(2) = 9

grab rope, tie a loop-de-loop, put it around ur neck, now jump while its tied to a high place. now your shoes are cool.

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
