Use the function f(x)=2^x/x to answer the question. Which combination could result in the function f(x)?

A dividing an exponential function by a linear function
B adding an exponential function and a linear function
C multiplying a quadratic function with a rational function
D adding a quadratic function and a rational function

Answer 1

A function is shown where b is a real number. f(x)=x^2+bx+144 The minimum value of the function is 80. Create an equation for an equivalent function in the form f(x)=(x-h)^2+k.
