What kind of graph would the function \(f(x)= 3x^{2} + 7\) make?

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.

\(y=x\)

\(y=\frac{1}{x}\)

\(y=5x^2-4x+1\)

\(y=x^3+2x^2-7\)
