Need help Please! Use the function f(x) to answer the questions: f(x) = 4x2 + 8x - 5 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 a minimum? What are the coordinates of the vertex? Justify your answers and show your work (3 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)​

Given function:

The x-intercept is the point(s) with y = 0

The leading coefficient is positive. It mean the graph opens up. It in turn means the vertex is the lowest point.

The vertex is defined by:

Plot the vertex (-1, -9), x-intercepts (0.5, 0) and (-2.5, 0) and connect the points considering the graph opens up. You may need to add more points to the graph if need more accurate graph.

452,489 to the nearest thousand is 452,000

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
