Caleb said that the function f(x) = x3 + x2 + x + 1 would be a Quadratic function and therefore make a u-shaped graph called a parabola. Is Caleb right? If not, what kind of function is this?
Part A
Match each function with the correct function family.
Linear | Quadratic | Cubic | Rational | |
---|---|---|---|---|
\(y=x\) | ||||
\(y=\frac{1}{x}\) | ||||
\(y=5x^2-4x+1\) | ||||
\(y=x^3+2x^2-7\) |
