**Answer:**

x equals 28

**Step-by-step explanation:**

16 + 12 = x because

Note that the first function is f(x) = 4 for x less than 2 and for the second function f(x) = -1 for x greater than or equal to 2

So the limit as x approaches two from the left is 4 and the limit as x approaches 2 from the right is -1.

so looks like you would need the third choice: 4; -1

So the limit as x approaches two from the left is 4 and the limit as x approaches 2 from the right is -1.

so looks like you would need the third choice: 4; -1

What is the rate of growth or decay?

What was the initial amount? 120000

What is the function?

What is the population after 10 years? Round to the nearest whole number.

**Answer:**

- Decay Problem.

- Decay rate, r = 0.014
- Initial Amount =120,000

- P(10)=104,220

**Step-by-step explanation:**

The exponential function for growth/decay is given as:

In this problem:

The city's** initial population is 120,000** and it **decreases by 1.4% per year.**

- Since the population decreases, it is a
**Decay Problem.**

- Decay rate, r=1.4% =0.014
- Initial Amount =120,000

Therefore, the function is:

When t=10 years

There are 95 cards did **Steve **initially **purchase **to begin his collection.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

**Steve **began a baseball card collection by purchasing some cards.

And, He **increased **the number of cards in the collection by a constant amount each week after that.

Now, In 3 weeks he collect 285 cards.

Hence, Number of **cards **to collect in initially is,

⇒ 285/3

⇒ 95

Thus, There are 95 cards did** Steve initially** purchase to begin his collection.

Answer:95

Step-by-step explanation:

95x3=285

B) f(x) = 8x3 − 24x2 − 48x + 64

C) f(x) = x3 + 3x2 − 6x − 8

D) f(x) = 8x3 + 24x2 − 48x − 64

Answer:

See image

Step-by-step explanation:

Check out the y-intercepts for these equations and look at the y-intercept on the graph. The y-intercept is the point where x=0. So it's mental math you can do in a couple of seconds per equation. If x=0 all the x terms are zero and the y-intercept is just the constant at the end if the equation. I put a note on the graph and the answer choices. The constant is the y-intercept. Only one choice matches. See images.

A) f(x) = x3 − 3x2 − 6x + 8
