Answer:

They are only equal on day 0, both having 10 population.

Step-by-step explanation:

Given the bacteria on the counter is initially measured at 5 and doubles every 3 days we can generate the following geometric equation:

f(x)=10*2^{\frac{x}{3} }

Given the bacteria on the stove is measured at 10 and doubles every 4 days we can create another equation:

f(x)=10*2^{\frac{x}{4} }

To find how many days it will take for the bacteria population to equal the same lets set both equations equal to eachother:

10*2^{x/3}=10*2^{x/4}

Divide both sides by 10

2^{x/3}=2^{x/4}

Since both exponents have the same base we can set the exponents equal to eachother and solve for x:

\frac{x}{3}=\frac{x}{4}

Multiply both sides by 3 to isolate x on the left side

x=\frac{3x}{4}

Multiply both sides by 4 to remove fraction

4x=3x

Subtract 3x to isolate x on the left side

x=0

Plug x into one of our original equations

f(0)=10*2^{0/3}

Solve

f(0)=10

If f(x)=4x^2-3 and g9x)=x+1, find (f-g)(x)
kiruha [24]

Step-by-step explanation:

(f-g)(x) = f(x) - g(x)

the same applies to all other basic operations (like addition, multiplication, ...).

so,

(f-g)(x) = 4x² - 3 - (x + 1) = 4x² - 3 - x - 1 = 4x² - x - 4
