Question 844857
{{{graph(350,350,-11,11,-2,20,x^2+3x,5x+3)}}}


{{{f=g}}} means {{{x^2+3x=5x+3}}}
{{{x^2-2x-3=0}}}
{{{(x-3)(x+1)=0}}}

The intersections are at {{{x=3}}} and {{{x=-1}}}.


Choosing either function to evaluate the vertical coordinate of each x value,
g(-1)=5(-1)+3=-2;
and
g(3)=5*3+3=18.
-
Intersection points are (-1,-2) and (3, 18).
