Okie, so a parent function is one that is the basic type of the graph. So, the best way to know is the exponents on the x's and or factored form etc. The function g(x) is easily determinable. Let's distribute g(x)
3(x-5) = 3x -15. This is the equation of a line with a slope of 3 and a y-intercept of -15. Therefore, the parent graph that is similar to it is the line graph y = x. I hope this helps :-)
