MEDAL FOR RIGHT ANSWER!!!

OpenStudy (graceland00):

Based on the graph below, what are the solutions to the equation f(x) = g(x)?

OpenStudy (graceland00):

OpenStudy (graceland00):

x = −2, 2, 3 x = −2, .5, 3.5 x = −2.8, 0.6, −3.7 x = −2, 1, 2

OpenStudy (welshfella):

The solutions are the 3 points where the 2 graphs intersect

OpenStudy (welshfella):

Hint: one such point is x = -2 . what are the other 2 intersections?

OpenStudy (michele_laino):

hint: we have to look for the intersection points between the graphs of \(f(x)\) and \(g(x)\)

OpenStudy (michele_laino):

as we can see from the drawing, the leftmost intersection point occurs at \(x=-2\)

OpenStudy (michele_laino):

now, please do the same for the other 2 intersection points

OpenStudy (graceland00):

so it's just where the lines intersect?

OpenStudy (michele_laino):

yes!

OpenStudy (graceland00):

So would it be B?
