Answer 1

Explanation:

1.(-1/2,-5/2),(2,5)

2.0

3.-1,19

4.-9,9

5.exponential

6.a

7.d

8.c

9.b

10.y=-2x^2+4 is just 4 units up from y=-2x^2

Answer 2

We can solve these equations by using substitution method where you substitute one equation to the other and solve for the value of the other variable. We do as follows:

y = 2x^2
y = –3x −1

2x^2 = –3x −1
2x^2 +3x +1 = 0

x1= -0.5
x2 = -1
y1 = 0.5
y2 = 2
