The graphs of f(x) and g(x) are shown below:
OpenStudy (anonymous):
What are the solutions to the equation f(x) = g(x)?
OpenStudy (anonymous):
The point on intersections
OpenStudy (anonymous):
So -10 and 12?
OpenStudy (anonymous):
Points have an x and y, so for example, (-1, -10), would be one

I know, but the thing is that the answer choices aren't written like that.
OpenStudy (anonymous):
x = -1, 5.4
x = -3, 4
x = -1, 2
x = -10, 12
OpenStudy (anonymous):
Yes
OpenStudy (anonymous):
So it would be D then?
OpenStudy (anonymous):
Is that what your saying yes to?

For example: f(-10) = n(-1) = g(-10)
jimthompson5910 (jim_thompson5910):
look at the x coordinates of the points
not the y coordinates
jimthompson5910 (jim_thompson5910):
when you have f(x) = g(x), you're ultimately solving for x
eg:
f(x) = 2x
g(x) = 5x+10
f(x) = g(x) turns into 2x = 5x+10 which solves to x = -10/3
OpenStudy (anonymous):
So -1 and 5.4?
OpenStudy (anonymous):
Yep

looks better
OpenStudy (anonymous):
Taylor, you just said D was the answer >:(
OpenStudy (anonymous):
Wot no
OpenStudy (anonymous):
Alright, well thanks Jim!
jimthompson5910 (jim_thompson5910):
no problem

OpenStudy (anonymous):
Lol sorry i thought it was until he said the thing about the x's my bad ;)
OpenStudy (anonymous):
Yeah, same. Thanks for trying to help though
