One number is 10 times as large as another, and their difference is 81. find the numbers. if x represents the smaller number, than the larger number is wyzant

Which is f(5) for the function –2x2 + 2x - 3?

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.

Which expression is equivalent to -12(3x-3/4)
