What’s the x-intercepts, vertex, y-intercept? y=(x+1)2-16

The vertex is (-1, -16)

x intercepts is : (3, 0) or (-5, 0)

y intercept is (0, -15)

Solution:

Given is:

The vertex form of an equation is given as:

Where, (h, k) is the vertex

On comparing the above equation with given,

h = -1

k = -16

Thus the vertex is (-1, -16)

To find the x-intercept, substitute y = 0 in given

Thus x intercepts is : (3, 0) or (-5, 0)

To find the y-intercept, substitute x = 0 in given

Thus the y intercept is (0, -15)

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.

answer is because 4×10=40

and 98×4= is 392

40,392
