Question

III.

Answer 1

Answer:

• The y-intercept is - 372 and it means that if the manufacturers do not produce and sell any blenders they will have a loss of $ 372.

Explanation:

The polynomial that represents the function is:

• $P(x)=8x+0.3x^2-0.0013x^3-372$

Where the variable, x, represents the number of blenders produced and sold monthly, and P(x) is the monthly profit in dollars obtained for the sale of x blenders.

As for the question, the y-intercept is the point on the graph where the function crosses the y-axis, i.e. where the input of the function is x = 0.

Therefore, the y-intercept is the value of the function for x = 0, P(0), and it is found by substituting 0 for x in the polynomial function, which is shown next:

• $P(0)=8(0)+0.3(0)^2-0.0013(0)^3-372=-372$

The meaning of this value is that the firm loses $372 when it does not produce and sell any blenders.
