Find the roots of the polynomial function f(x) = x^3 + 2x^2 + x

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^x

Given the quadratic function f(x)=3x^2-24x+49 a. use “completing the squares” to convert the quadratic function into vertex form b. state the vertex c. find the x and y intercepts d. graph the function
