    f(x)=4*7(-1)=? f(x)=4*7(2)=? You can plug it into your calculator to get your answer

    Ya all you need to do is put your values of x into the x spot, each time, of your equation to solve.

    The answer would be like this I will do the one where x = -1 f(x)=4*7(-1)= -28 So f(x) = -28 when x = -1 OR f(-1) = -28 There are a few ways to write it.
