What is the maximum number of possible extreme values for the function, F(x)=x^4+x^3-7x^2-x+6?

Arturiano [62]

Coming from a 6th grader but I hope this is right!

Polynomials of degree greater than 2 can have more than one max or min value. The largest possible number of minimum or maximum points is one less than the degree of the polynomial. The following examples illustrate several possibilities.

since the degree is 4

number of possible extreme values = 4 -1 = 3

Most plumbing companies charge a fee to come to your house plus a charge per hour of work. The fees and charges for two plumbing

lord [1]

Answer:

Company A: $y=40x+50$

Company B: $y=50x+25$

Step-by-step explanation:

The initial fee is the y-intercept, as that is the cost at x = 0, or the cost before any time has passed. Afterwards, the rate the cost increases is the slope.

Linear equation in slope-intercept form:

$y=mx+b$

where m is the slope and b is the y-intercept.

Company A charges $50 up front and $40 per hour afterwards, so the equation would be:

$y=40x+50$

Company B charges $25 up front and $50 per hour, so:

$y=50x+25$
