Answer:

x-intercept : None

y-intercept : (0, -24)

Vertex : (4, -8)

Focus : (4, -33/4)

Axis of Symmetry : x = 4

Directrix : y = -31/4

Step-by-step explanation: Use the vertex form to determine the values of a, h, and k and use these values to find the direction the parabola opens, vertex, focus, axis of symmetry, and directrix.

Profit, or the surplus money after your costs are covered, is Revenue - Costs.

so in this case the profit P(x) = R(x) - C(x).

$\bf P(x)=(135x)-(93x+35000)\implies P(x)=135x-93x-35000
\\\\\\
P(x)=42x-35000

P(5000)=175000$
