An object was launched off the top of a building. The function f(x)=-16x^2+32x+48f(x)=−16x 2
+32x+48 represents the height of the object above the ground, in feet, xx seconds after being launched. Find and interpret the given function values and determine an appropriate domain for the function.

i believe the answer is the polygon, heptagon.

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
