Question

The number of members f(x) in a baseball club increased by 45% every year over a period of x years. The function below shows the relationship between f(x) and x:

f(x) = 25(1.45)x

Which of the following graphs best represents the function?

Graph of f of x equals 1.45 multiplied by 25 to the power of x
Graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity
Graph of f of x equals 1.45 to the power of x
Graph of f of x equals 25 multiplied by 1.45 to the power of x

Answer 1

Graph of f of x equals 25 multiplied by 1.45 to the power of x

Explanation:

This is because the 25 in the equation is put in the graph, I suck at alegbra but one day I'll be great at it hopefully...

Answer 2

The correct option is D) Graph of f of x equals 25 multiplied by 1.45 to the power of x

Explanation:

Consider the provided function.

`f(x) = 25(1.45)^x`

First draw the graph of the function with the help of the table.

x -1 0 1 2

f(x) 17.24 25 36.25 52.5625

The graph of the function is shown below:

The word form of the above function is:

The graph of function f(x) is equal to 25 multiply by 1.45 to the power of x.

Hence, the correct option is D) Graph of f of x equals 25 multiplied by 1.45 to the power of x
