How does the graph of the following function compare with the graph of the parent
function, y =log bx
OA.
OB.
y = log 5x + 1
Choose the correct graph to the right

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

answer is  

d.

a circle

i got it down for you chief.
