If g (x) = 2x + 3 and f (x) = x

2 - 49x, find all solutions of the equation f (g (x)) = 0.

Basically you just have to plug in g (x) wherever you see an x in the equation f (x) since x is f (x) you just substitute it. So f (g (x)) = 2x+3

You then just have to solve for 0

0=2x+3

Subtract 3 from both sides

-3=2x

Divide by 2

X=-3/2
