    for the first one just read off the values of g(x) corresponding to x = -5

    this gives you the value of g(x) when x = -5 it is written as g(-5)

    For the second question the function will be of the form f(x) = nx + 5 because when x = 0, f(x) = 5 ( check the table) f(x) = 0*n + 5 = 5 (0 times n = 0)

    now need to find the value of n we see from the table that f(x) = 8 when x = 1 so 8 = n + 5 can you solve this for n?

    right so it looks like the function is 3x + 5 lets check it out with the third row of the table when x = 2 , f(x) = 11 so if we plug these values into f(x) = 3x + 5 we get 11 = 3* 2 + 5 is that correct? does 3*2 + 5 = 11?

    This is the answer key f(x)=x+5 f(x)=8x f(x)=3x+5 f(x)=5x-3
