Question

hello what are two real word examples of exponential functions???

Answer 1

Exponential Functions

Here's what exponential functions look like:

y=2xy=2x

The equation is y equals 2 raised to the x power. This sort of equation represents what we call "exponential growth" or "exponential decay." Other examples of exponential functions include:

y=3xy=3xf(x)=4.5xf(x)=4.5xy=2x+1y=2x+1

The general exponential function looks like this: y=bxy=bx, where the base b is any positive constant. The base b could be 1, but remember that 1 to any power is just 1, so it's a particularly boring exponential function!

Let's try some examples:

Example 1

Solve for x: 4=2x4=2x

This one is actually pretty simple, so let's just think it through:

The problem says we have to multiply x number of two's together to get four. Well, everyone knows that 2∗2=42∗2=4, so the answer is two:

4=2x4=2xx=2x=2

Hope this helped!!!
