How many points of intersection are there between the graphs of y=(x^2) and y=-3?

• 0

• 1

• 3

• 4

Answer explanation

If you notice the blue line y=-3 and the red quadratic y=(x^2) do not cross so the point of intersection is none.

How many points of intersection are there between the graphs f(x)=(-x^2)+3 and g(x)=1

Use Calculator :)

• 4

• 2

• 1

• 0

Answer explanation

g(x)=1 intersected with f(x)=(-x^2)+3 twice give this system two solutions.

The Quadratic and Linear Systems DO NOT intersect so there are _________ solutions.

Answer explanation

No solutions, none, zero
