How many times does the graph of the function below intersect or touch the x-axis? y=-3x^2+x+4 ...?

2 answers:

8 0

when the graph touches x axis at that point y = 0

 So, putting y =0
0 = -3x^2 + x +4
so, if you factoriazte it

−3x^2++4x−3x+4=0

 −3x(x+1)+4(x+1)=0

 (x+1)+(−3x+4)=0

 x=−1,4/3

So, two time at -1 and 4/3 it touches the x-axid

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

\stackrel{\textit{selling 5000 mp3s}}{P(5000)=42(5000)-35000}\implies P(5000)=210000-35000
\\\\\\
P(5000)=175000$
