Question

An expression is shown below:

HELP PLEASE THIS IS THE LAST QUESTION AND IM STRUGGLING!!! PLEASE!!!!

f(x) = -16x2 + 24x + 16

Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)

Part B: Is the vertex of the graph of f(x) going to be a maximum or minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)

Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)

Answer 1

help

Answer 2

A set it equal to zero and solve
divide by 8 first

B the first coordinate of the vertex is of \(y=ax^2+bx+c\) is \[-\frac{b}{2a}\] to get the second coordinate, plug that in for \(x\)

Answer 3

ok great
