Ali graphs the function f(x) = –(x + 2)2 – 1 as shown. which best describes the error in the graph? the axis of symmetry should be x = –1. the axis of symmetry should be x = 2. the vertex should be a maximum. the vertex should be (–2, 1).

the vertex should be a maximum

Step-by-step explanation:

given y = - (x + 2)² - 1

compare to equation in vertex form

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

⇒ vertex = (- 2, - 1) ← correct

the axis of symmetry passes through the vertex , is vertical with equation

x = - 2 ← correct

• If a > 0, then vertex is a minimum

• If a < 0, then vertex is a maximum

here a < 0 ⇒ vertex should be a maximum

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
