Use the graph of f to estimate the local maximum and local minimum. A cubic graph is shown increasing, then decreasing, then inc
Lina20 [59]

Graph is missing but we can still solve this problem using given information.

Given that graph is cubic which increases first then decreases then increases again. The graph intercepts the x axis at approximately -1.8, 0, and 3.2.

That means graph will look similar to attached graph.

We can see that maximum lies at point A Which is clearly between x=-1.8 and x=0

That best matches with x=-1 from given choices.


We can see that minimum lies at point B Which is clearly between x=0 and x=3.2

That best matches with x=2 from given choices.


Hence final answer is "Local maximum: approx. (-1,1.17); local minimum: approx. (2,-3.33)"

Use the following graph to estimate the rate of change of the function at x=0.6 using the points (0,0) and (1,−0.5)
svetoff [14.1K]

Answer:

The rate of change of the function at x = 0.6 is approximately -0.72

Step-by-step explanation:

The given information from the graph are;

Points (0, 0) and (1, -0.5)

We have that the graph is that of a cubic function, therefore;

f(x) = ax³ + bx² + cx + d

At f'(x) at  (0, 0) and (1, -0.5) = 0 gives;

3ax² + 2bx + c = 0

∴ c = 0

Also

ax³ + bx² + cx + d = 0

d = 0

We have

3a(1)² + 2b(1) + 0 = 0

3·a + 2·b = 0..............(1)

a(1)³ + b(1)² + c(1) + d = -0.5

a + b + 0×(1) + 0 = -0.5

a + b = -0.5..........(2)

Multiplying equation (2) by 2 and subtracting it from equation (1) gives;

2 × (a + b = -0.5) = 2·a + 2·b = -1

3·a + 2·b - (2·a + 2·b) = 0 - (-1) = 0 + 1 = 1

a = 1

From

a + b = -0.5, we have;

1 + b = -0.5 = 0

b = -0.5 - 1 = -1.5

The equation becomes

f(x) = x³ - 1.5·x²

The rate of change of the function at x = 0.6 is therefore given as follows;

f'(x) = 3 × x² - 2 × (1.5)·x = 3·x² - 3·x

At x = 0.6, we have;

f'(0.6) = 3·(0.6)² - 3·(0.6)

f'(0.6) = 3×0.6² - 3×0.6 = -0.72

The rate of change of the function at x = 0.6 ≈ -0.72

1. A certain store sells 2-liter bottles of pop for $1.19. They have a special on a 6-pack of 12 ounce cans for $1.50. (A 2-lite
Flura [38]
1:  1.19 for 67.2 ounces is about 1.77 cents per ounce.  However, $1.50 for 72 ounces is about 2.08 cents per ounce.  Clearly, then, the first bottle is cheaper.

2.  We simply divide 3/4 by 2 to get (3/4)/2=3/(4*2)=3/8.

3.  If the length of the second is 20 feet compared to a 2-foot length for the first, the width of the second rectangle will be ten times the width of the first, so the width of the second rectangle is 10*8=80.
