The fish population in a local lake is 10,000. The population increase by half every year. Which function represents the fish po
sweet-ann [11.9K]

Answer:

5. f(x) = 10,000 (1.5)^x

Step-by-step explanation:

We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.

Let's test it.

Initial:

10,000

After 1 year

10,000 + (.5*10000)

10,000 + 5000 = 15,000

After 2 years

15,000 + (.5*15000)

15,000 + 7500 = 22,500

Let's try our equation.

f(x) = 10,000 (1.5)^x

x = 2

10,000(1.5)^2

10,000(2.25) = 22,500

The same!

Which results only in a horizontal compression of y=1/x by a factor of 6
yan [13]

we are given

parent function as

y=\frac{1}{x}

Suppose, we are given a function y=f(x) is compressed horizontally by ''b'' units

where b>1

so, we can write as

new function as

y=f(bx)

Here, it is compressed by factor 6

so, we can replace x as 6x

and we get

y=\frac{1}{6x}

so, option-A.........Answer

Alisiya [41]

Answer:

No solutions.

Step-by-step explanation:

x - y = 2   <Start with an equation

x - (x + 2) = 2   <Plug in the given y value and solve for x

x - x - 2 = 2   <Combine like terms

0 - 2 = 2   <There are no values of x

No solutions.
