You have two exponential functions. One function has the formula g(x) = 3 x . The other function has the formula h(x) = 2-x . Which option below shows the graph of k(x) = g(x) - h(x)?

Respuesta :

Shown below

Explanation:

The options aren't provided. However, we can answer this question. Here we have two exponential functions:

[tex]g(x)=3^x \\ \\ h(x)=2^{-x}[/tex]

  • The function g(x) is an exponential growth.
  • The function h(x) is an exponential decay.

So we are asked to find another function k(x):

[tex]k(x)=g(x)-h(x)[/tex]

In this new function we subtract h(x) from g(x), so:

[tex]k(x)=3^x-2^{-x}[/tex]

By using graphing tool, we get the graph as shown below. Notice that this graph passes through the origin because:

[tex]k(0)=3^0-2^{-0} \\ \\ k(0)=1-1 \\ \\ k(0)=0[/tex]
