Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: ( − ∞ , ∞ ) , { x | x ∈ R }

Range: ( − ∞ , 16 ] , { y | y ≤ 16 }

Can someone please help me with this equation, ill give brainest to the person who is correct.
ohaa [14]
5x means that 5 should be multiplied by the value of x
Every time a variable is touching a number it means it’s multiplying

5x + 8 = ?

If x = 9, you would multiply 5 and 9 which is 45. You then add 45 and 8

45 + 8 = 53

Therefore 5x + 8 = 53

Hope this helps you! :)

The function f(x) = 25(4)^x represents the growth of a bird population every year in a national park. Kyle wants to manipulate t
Natasha_Volkova [10]

f(x)=25(4)^{\frac{x}{2}} will be the function to calculate population every half year.

Further explanation:

The given formula is:

f(x) = 25(4)^x

In the given formula, x represents the amount of time in years. So, in order to convert the given function for yearly calculation of population, to find the population every half year the time will be converted into half. This means that instead of x, x/2 will be used.

So the new function will be:

f(x) = 25(4)^{\frac{x}{2}}

Keywords: Population growth, Population growth function
