Use the Graph of the Function to Estimate the X-Intercepts $X - 15$

question 215

Multiple Choice

Use the graph of the function to estimate the x-intercepts.
-At Allied Electronics, production has begun on the $X - 15$ Computer Chip. The total revenue function is given by $R ( x ) = 50 x - 0.3 x ^ { 2 }$ and the total cost function is given by $C ( x ) = 8 x + 10$ , where $x$ represents the number of boxes of computer chips produced. The total profit function, $P ( x )$ , is such that $P ( x ) = R ( x ) - C ( x )$ . Find $P ( x )$ .

• A) \(P ( x ) = - 0.3 x ^ { 2 } + 42 x - 10\)
• B) \(\mathrm { P } ( \mathrm { x } ) = 0.3 \mathrm { x } ^ { 2 } + 42 \mathrm { x } - 20\)
• C) \(P ( x ) = - 0.3 x ^ { 2 } + 34 x + 10\)
• D) \(\mathrm { P } ( \mathrm { x } ) = 0.3 \mathrm { x } ^ { 2 } + 34 \mathrm { x } - 30\)
