Let f be the function defined by 9+2 3 (a) determine the y-intercept. (b) determine the horizontal and vertical asymptotes. (c) use the sign pattern for f"(x) to determine (i) the interval(s) over which f rises and where it falls; (ii) the local extrema (d) use the sign pattern for f"(ax) to determine (i) where the graph of f is concave up and where it is concave down; (i) the inflection point(s) (if any).

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
