Question

I need help with math

Answer 1

Zeros

Values when y=0 or when the line bisect the x-axis, we take this values and change the sign, because if we replace this values on the equation of the fuction we will obtain 0 as solution

`\begin{gathered} x=-4 \\ x=0 \end{gathered}`

Range

all possible values for y, then we can notice the highest vulue is 4 , so values of y must be less than or equal to 4

`y\le4`

Axis of symmetry

line that divides the parabola into two equal parts

`x=-2`
