Find the y-intercept for the graph of the quadratic function. y + 4 = (x + 2)2

y-intercept is equal the value of function for x = 0.

Put x = 0 to the equation y + 4 = (x + 2)²

y + 4 = (0 + 2)²

y + 4 = 2²

y + 4 = 4     |-4

y = 0

y-intercept = 0 → (0, 0)

answer: 590

step-by-step explanation:

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
