PLEASE I NEED HELP Pierre was plotting the quadratic function f(x)=-x^2+8x for an exit ticket. his work is shown to the right.

Part A: Complete the table below and graph function on the same coordinate system above.
X f(x) X f(x)
0 5
1 6
2 7
3 8
4

Part B: His teacher marked it incorrect. Explain why Pierre's work was counted incorrect.

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.

step-by-step explanation:

the one below it is a function

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°

daren is correct because
