The axis of symmetry for a function in the form f(x) = x2 + 4x − 5 is x = −2. what are the coordinates of the vertex of the graph?
(−9, −2)
(−17, −2)
(−2, −17)
(−2, −9)

Option D is correct.

The coordinate of the vertex of the graph is, (-2, -9)

Step-by-step explanation:

Given the function:

it is given that: the axis of symmetry for a function is, x = -2

Also, the axis of symmetry divides the parabola into two equal parts.

So,  if there is a point on one of the side, there is a  corresponding point on the other side that is the same distance from the axis of symmetry and has the same y-value.

Also, the x-coordinate of the vertex is x = -2.

Substitute the x values in the original equation to find the value of y;

Simplify:

Therefore, the coordinate of the vertex of the graph is, (-2, -9)

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
