What are the solutions of the equation f(x)=g(x) <br> 0<br> 1<br> 2<br> 3<br> 4
Alex

Answer:

(1, 0 ) and (3, 6 )

Step-by-step explanation:

we are looking in the table for values of x that give both f(x) and g(x) the same value.

x = 1 → f(x) = g(x) = 0

x = 3 → f(x) = g(x) = 6

then the solutions to f(x) = g(x) are

(1, 0 ) and (3, 6 )
