Step-by-step explanation:

First put it in point slope for y = mx + b

y = -2x + 5

Now plug in what ever number you want for x and solve.

Given that (-3,1) is on the graph of f(x), find the corresponding point for the function f(x-1)

Helen [10]

Answer:

(-2,1)

Step-by-step explanation:

So we are given f(-3)=1 since the point (-3,1) is on f(x).

We want to use this point to find a point on f(x-1).

Now,

f(-3)=1

and we want

f(x-1)=1

What would x need to be such that x-1 is -3.

x-1=-3

Add 1 on both sides:

x=-3+1

x=-2

x would need to be -2 in f(x-1)=1 in order to use that f(-3)=1.

So (-2,1) is the point for the function f(x-1) that corresponds to the point (-3,1) for f(x).

I know that f(x-1) would only be effecting our input because x-1 is the input.

A certain culture of year increases by 50% every three hours. A scientist places 9 grams of yeast in a culture dish. Write the e

miskamm [114]

Answer: a) Explicit formula : $f(x)=9(1.5)^{3x}$

b) Recursive formula : $f(x)=9(1.5)^{3x}$ and $f(x+1)=f(x)\times 1.5^3$

Step-by-step explanation:

Since we have given that

Number of grams of yeast in a culture dish initially = 9 grams

According to question, a certain culture of year increases by 50 % every three hours.

So, the explicit formula will be

$f(x)=9(1+\frac{50}{100})^{3x}\\\\f(x)=9(1+0.5)^{3x}\\\\f(x)=9(1.5)^{3x}$

And the recursive formula will be

$f(x)=9(1.5)^{3x}\\\\f(x+1)=9(1.5)^{3(x+1)}\\\\f(x+1)=9(1.5)^{3x+3}\\\\f(x+1)=9(1.5)^{3x}.(1.5)^3\\\\f(x+1)=f(x)\times 1.5^3$

Hence, a) Explicit formula : $f(x)=9(1.5)^{3x}$

b) Recursive formula : $f(x)=9(1.5)^{3x}$ and $f(x+1)=f(x)\times 1.5^3$

A drug that it will decrease the bacteria cells by 5% every hour. If you start with 1500 bacteria cells, how many will be presen

scZoUnD [109]

after 8 hours there are 995 bacteria cells left

let y be the amount after 8 hours

the multiplying factor is 100 - 5 = 95 % = 0.95

y = 1500 × $(0.95)^{8}$ = 995
