Help for medal and fan?!?!

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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?

OpenStudy (anonymous):

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

jimthompson5910 (jim_thompson5910):

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):

Haha, nice try taylor

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

OpenStudy (anonymous):
