1) increasing on (-∞,-1] ∪ [1,∞), decreasing on [-1,0) ∪ (0,1]

is local maximum, is local minimum

2) increasing on [1,∞), decreasing on (-∞,0) ∪ (0,1]

is absolute minimum

3) increasing on (-∞,0] ∪ [8,∞), decreasing on [0,4) ∪ (4,8]

is local maximum, is local minimum

4) increasing on [2,∞), decreasing on (-∞,2]

is absolute minimum

5) increasing on the interval (0,4/9], decreasing on the interval [4/9,∞)

is local minimum, is absolute maximum

Step-by-step explanation:

To find minima and maxima the of the function, we must take the derivative and equalize it to zero to find the roots.

1)

and

So, the roots are and

The function is increasing on the interval (-∞,-1] ∪ [1,∞)

The function is decreasing on the interval [-1,0) ∪ (0,1]

is local maximum, is local minimum.

2)

and

So the root is

The function is increasing on the interval [1,∞)

The function is decreasing on the interval (-∞,0) ∪ (0,1]

is absolute minimum.

3)

and

So the roots are and

The function is increasing on the interval (-∞,0] ∪ [8,∞)

The function is decreasing on the interval [0,4) ∪ (4,8]

is local maximum, is local minimum.

4)

has no solution and is crtitical point.

The function is increasing on the interval [2,∞)

The function is decreasing on the interval (-∞,2]

is absolute minimum.

5) for

So the root is

The function is increasing on the interval (0,4/9]

The function is decreasing on the interval [4/9,∞)

is local minimum, is absolute maximum.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
