An airplanes altitude changed -531 feet over 9 minutes. what was the mean change of altitude in feet per minute.

Find the zero function by factoring (try to show work) h(x)=-x^2-6x-9

What is the prime factorization of 23 ?me with this question

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.
