I need alot of help with f(x) = x2 + 9x – 36 because i have an assignment due later tonight and it will bring my grade down majorly

so if the x2 is x squared and you are trying to find the values of x where f(x) is 0 then they are -12 and 3

Step-by-step explanation:

we can factor these into (x+12)(x-3)

in order for (x+12)(x-3) to be 0 then one of them has to be 0

first is (x+12) = 0 so x is -12

second is (x-3) = 0 so x is 3

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
