In the function y = -5x2 + 5 , the graph will open down, be shifted up 5 units, and it will be wider than the parent function y
masya89 [10]
We are considering the function y=f(x)=-5 x^{2} +5

the graph of this function is the graph of the parent function y=g(x)= x^{2} after applying the following steps.

1. multiply by -1:

-x^{2} is x^{2} reflected with respect to the x-axis.


2. multiply by 5:

-5x^{2} is -x^{2} shrinked towards the y axis. 

for example, consider x=1/2

 -5x^{2}=-5( \frac{1}{2} )^{2}=-5* \frac{1}{4}= \frac{-5}{4}=-1.25

 -x^{2}=- ( \frac{1}{2} )^{2}=- \frac{1}{4}=-0.25

now this means that -5x^{2} is "lower" than -x^{2}, which means there is a shrinking of the graph.

3. add 5:

-5 x^{2} +5 is -5 x^{2} shifted 5 units up.


4.

so the graph of the function a) opens down, b) is shifted 5 units up, c) is not wider than the parent function
