Answer:

Find the solution set of this system:
bezimeni [28]

Answer:

(−4, 12), (1, −3)

Step-by-step explanation:

y = −3x

x^2 −4 = y

so

x^2 −4 = −3x

x^2 + 3x - 4 = 0

(x + 4)(x - 1) = 0

x + 4 = 0; x = -4

x - 1 = 0; x = 1

when x = 1, y = -3(1) = -3

when x = -4, y = -3(-4) = 12

Answer

(-4 , 12), (1 , -3)

We're given a parabola

y=x^2-4

and a line

y = 2x+b

The zeros of the parabola are

0=x^2-4

4=x^2

x=\pm 2

We see that (-2,0) is on the line as well:

y = 2x+b

0 = 2(-2)+b

b=4

Choice D
