I suck at rounding so this is the answer not rounded
Answer:
(x,y)=(-2,-5)
Step-by-step explanation:
y=1/2x-4
y=-2x-9
(y=) 1/2x-4=-2x-9
1/2x +2x=-9+4
1/2x +4/2x=-5
5/2x=-5
5x=-5*2
5x=-10
x=-2
x=-2
y=-2x-9=-2*(-2)-9=4-9=-5
(x,y)=(-2,-5)
Answer:
I thinks no for all except the last one.
Plug in -2 to x in the formula
So f(-2)= ((-2)+1)^2
Your answer should be: 1
