Question

Select the exponential function that represents a population of 800 salmon that is growing at a rate of 11% per year.(1 point)
Responses

f(x)=(800⋅1.11)x

f of x is equal to open paren 800 times 1 point 1 1 close paren to the x th power

f(x)=800(1.11)x

f of x is equal to 800 times 1 point 1 1 to the x th power

f(x)=800(0.11)x

f of x is equal to 800 times 0 point 1 1 to the x th power

f(x)=800(0.89)x

Answer 1

f(x) = 800(1.11)^x

Explanation: growth by 11% per year means multiply by 1 + 0.11 = 1.11 each year, so f(x) = initial amount · (1.11)^x.
