How do you simplify the y-terms to get the equation of the parabolic path for (√(X-3)^2+(y-7)^2)^2=(y-4)^2? So far i've gotten too (X-3)(X-3)+(y-7)(y-7)=(y-4)(y-4)

Given f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)

Offering 30 if a plus b plus c equals 68 and ab plus bc plus ca equals 1121, where a, b, and c are all prime numbers, find the value of abc. the answer is 1978 but i need an explanation on how to get that.

What is the value of f(x) = 2.2 for f(-2)?
