Consider the quadratic function f(x) = 2x² - 14x + 26. Part A: Graph f using a calculator or app. Use the graph to estimate the portion of the domain on which the function is increasing. Write your answer using interval notation. The function is increasing on the interval Part B: You learned earlier that the vertex may be found using the formula B B (-2 ƒ(-2/4)). 2A are seeing on your graph? " 2A Answer: Part C: Rewrite the formula f(x) = 2x² 14x + 26 in vertex form, f(x) f(x): . Use this formula to find the vertex. Does the result agree with what you - = A(x - H)² + K. Part D: Find a formula for the inverse of the function f, restricted to the portion of the domain on which f is increasing. f-¹(x) = Consider the quadratic function f(x) = 2x² - 14x + 26.
