1. Find the inverse function of f.
f(x)= -8+squareroot of -5+3x.
2. Write an equation of the parabola in standard form. (The points on the graph are (-1,-2)(0,-1)
3. Find the values of b such that the function has the given minimum value. f(x)= x^2+bx-20; minimum value: -29
-i Got 10 and -10 but it says it's wrong so i don't know.
4.Find all values of k such that f(x) is divisible by the given linear polynomial: f(x)= kx^3+x^2+k^2x+3k^2+8; x+2
