Use the function f(x) = −16x2 + 22x + 3 to answer the questions. Part A: Completely factor f(x). (2 points) Will give brainliest and 100 points Part B: What are the x-intercepts of the graph of f(x)? Show your work. (2 points) Part C: Describe the end behavior of the graph of f(x). Explain. (2 points) Part D: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part B and Part C to draw the graph. (4 points)

Part A: -(2x - 3)(8x + 1)

Part B: (-0.125, 0), (1.5, 0)

Part C: As x goes to infinity, f(x) goes to negative infinity. As x goes to negative infinity, f(x) goes to negative infinity.

Part D: I would find the zeroes and the vertex and draw the graph.

Step-by-step explanation:

For Part A, simply just factor the quadratic and you should get -(2x - 3)(8x + 1).

For Part B, use a graphing calculator and find where the graph crosses the x-axis. Where is does cross is where your zeros are.

For Part C, simply see what the values go to when we go to either infinity or negative infinity. Since the graph is a parabola goes down, we go to negative infinity.

For Part D, you only need 3 vital points to graph: The zeros and the vertex. Find those and you should be able to graph. Alternatively, you could use a graphing calc.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
