Find the percent of increase from 20 to 50

What is the equation of the linear function represented by the table?

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

Drag the tiles to the table. the tiles can be used more than once. nd g(x) = 2x + 5 model a similar situation. find the values of f(x) and g(x) let's say that the functions f(x for the given values of x. fix)=5(4) * g(x) = 2x+5
