Chapter 9.9, Problem 27PPS

To determine

To calculate: To identify the function as linear, quadratic, cubic or exponential function

Answer to Problem 27PPS

  $y=2\cdot 4^x$ isan exponential function

Explanation of Solution

Given information: Function is $y=2\cdot 4^x$

Formula Used:

Highest power of the variable in a function is referred to as degree of function.

Linear function is a function with degree 1

Quadratic function is a function with degree 2

Cubic function is a function with degree 3

Exponential function is a function with variable as exponent

Calculation:

Function is given as

  $y=2\cdot 4^x$

Here, exponent is a variable

Therefore, it’s an exponential function

Conclusion:

Hence, $y=2\cdot 4^x$ is an exponentialfunction.
