Jillian simplified the expression 7+3⋅(10−6)2 in the following way: 7+3⋅(10−6)2
7+3⋅(4)2
7+3⋅16
10⋅16
160
Part A: Explain, using complete sentences, what Jillian's error was.

Part B: Show how the expression should have been simplified using a similar format.

In which form is the following function written? y = - 2(x – 3)(x + 5)

Parabolas y=−2x^2 and y=2x^2 +k intersect at points a and b that are in the third and the fourth quadrants respectively. find k if length of the segment ab is 5.

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
