Question

Annual profit in thousands of dollars is given by the function, P(x) = -.1x2 + 50x - 300, where x is the number of items sold, x ¡Ý 0.
find the profit for 5 different values of x

Answer 1

I am pretty sure you meant
P(x) = -.1x^2 + 50x - 300

e.g. x = 4
P(4) = -.1(4^2) + 50(4) - 300
= -1.6 + 200 - 300
= -101.6

Pick any other 4 values of x , and follow my steps
