1.) Consider the graphs x+5y=17 and x+7=y^2 where a=7 b=2 c=57 f(x) = ? g(x) = ? I have solved for a,b, and c but I can't figure out f(x) and g(x) For f(x) I thought it was (17-x)/5 but it's not the correct answer. For g(x) I thought it was the sqrt(x+7)

I have tried solving this problem over and over but I'm still not sure with my answer. The question is sqrt2 / 2 + sqrt2. I think the answer is 1/sqrt2 + sqrt2 because you have to cancel out the common factors.
