Question

The vertex parabola is (-2,-3) when the x value is -1 the y-value is -5 what is the coefficient of the squared expression in the parabolas equation

Answer 1

-2

Explanation:

just did it on a p e x

Answer 2

The equation can be written in vertex form as
y = a(x +2)² - 3
Substituting the given values, we can find the coefficient "a".
-5 = a(-1+2)² -3
-2 = a . . . . . . . . . add 3 and simplify

The coefficient of the squared term is -2.
