Question

How many times does the graph of y = 1 intersect the graph of y = x^2 + 1

Answer 1

If you don't know this off the top of your head you could plug in 1 for y and solve for x. This is solving for the intersecting points.

Answer 2

How far have you gotten in this problem?

Answer 3

I dont understand it. Im retaking test from past modules and I realized i forgot alot of this stuff..

Answer 4

y= 1 is a strait horizontal line

the other function is a u shaped graph shifted up one I think it either tangent and it does touch once.

Answer 5

two times try to draw grap then put x and y value y is strait line but x is parabola

Answer 6

It hits once. at the minimum

Answer 7

so it intersects twice?

Answer 8

once

Answer 9

tangent to the curve

Answer 10

Solving by algebra:

y=1
y=x^2+1

Set equal
1=x^2+1
0=x^2
x=0

plug in 0 for x
y=1
(0,1) only point
