Question

I need help quickly so i can finish my homework in time

1. How is the graph of y = -2x^2-5, different from the graph of y = -2x^2

It is shifted 5 units up.
It is shifted 5 units down.
It is shifted 5 units left.
It is shifted 5 units right.

Answer 1

I really don't understand the graphing part because I don't know how to graph the equations

Answer 2

I just need help understanding it plz

Answer 3

\(\large \begin{array}{llllll}
y = -2x^2&{\color{red}{ -5}}&y = -2x^2&{\color{red}{ +0}}\\
&\uparrow &&\uparrow \\
&\textit{vertical shift}&&\textit{vertical shift}
\end{array}\)

Answer 4

So the second equation is 5 points down on the graph?

Answer 5

yeap

check your "function transformations" material
thus is a vertical shift down by 5 units from its "parent" function
