Question

What are the x– and y–intercepts of the quadratic equation y = (x – 1)2 – 16? Identify the x–intercepts by graphing the quadratic equation.

x–intercepts: (3, 0) and (–5, 0)
y–intercept: (0, –16)

x–intercepts: (–3, 0) and (5, 0)
y–intercept: (0, –16)

x–intercepts: (3, 0) and (–5, 0)
y–intercept: (0, –15)

x–intercepts: (–3, 0) and (5, 0)
y–intercept: (0, –15)

Answer 1

To find the x-intercept's, set y equal to 0.

0 = (x - 1)^2 - 16
16 = (x - 1)^2
(x - 1) = ±4
x = -3 or x = 5
So (-3, 0) and (5, 0) are coordinates of the x-intercepts.

To find the y-intercepts, set x equal to 0.
y = (0 - 1)^2 - 16
y = 1 - 16
y = -15

Answer 2

Wait is that 2 a regular 2 or an exponent ^2?

Answer 3

I think the answer is D

Answer 4

an exponent 2

Answer 5

ok then its D for sure

Answer 6

thank you brandy!!!
