Find a possible formula for the function graphed below Assum
Find a possible formula for the function graphed below Assume the function has only one x-intercept at the origin, and the point marked on the graph below is located at (6, 3/4) The asymptotes are x = -2 and x = 5 Give your formula as a reduced rational function.
Solution
asymptotes at x=-2, x=5
factors (x+2),(x-5) lies in the denominator
x intercept at origin
=>x-0 =x lie in numerator
general form of function that can be deduced from the given information is is y =ax/(x+2)(x-5)
given (6,3/4) lies on the graph
(3/4) =a*6/(6+2)(6-5)
(3/4) =a*6/8
a=1
therefore the possible function is f(x) =x/(x+2)(x-5)
