Question

I thought i knew it but i don’t think i do

Answer 1

f(x)=g(x)

SIMPLY MEANS YOU ARE TO FIND THE VALUES OF X FOR WHICH THE GRAPH OF F(X) IS EQUAL TO THE GRAPH OF G(X)

YOU CAN SEE THEY ARE EQUAL WHEN

`x = - 2.1 \\ x = 1.5 \\ x = 3.9`

THE ONLY OPTION AVAILABLE IS 3.9 THEREFORE THE ANSWER IS

`x = 3.9`

GOODLUCK.
