#1**+2 **

Here you go for the first one : https://www.desmos.com/calculator/ofobm3u4af

For the second

You have the correct graphs...the intersection points are ( -1, -3) and ( 3,5)

Algebraically....set the functions equal

x^2 -4 = 2x - 1 rearrange as

x^2 - 2x - 3 = 0 factor

(x - 3) ( x + 1) = 0

Set each factor and solve for x

x -3 = 0 x + 1 = 0

x = 3 x = -1

Put these values into either function for x and you should get the same intersection points as above

Hope that helps !!!
