Is knowing the coordinates of the vertex of a parabola enough to determine the domain and range? a. No: we would have no information about the domain

b. No: we would need to know if the vertex is a minimum or maximum

c. Yes: if the vertex is at (m, n), then information about the
the domain is all reals and the
domain range is y < n.

d. Yes: if the vertex is at (m, n), then the domain is all reals and the range is y > n.

hope this !

let me know

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
