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)

answer:

125 yards

explanation:

75+50=125. that is my answer

thus, the first answer choice, y = sec x, is the correct one
