Chapter 9.9, Problem 25PPS

To determine

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

Answer to Problem 25PPS

  $y=3x^2+4x$ is quadratic function

Explanation of Solution

Given information: Function is $y=3x^2+4x$

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

  $y=3x^2+4x$

Here, highest power of variable is $2$

Thus, degree of the function is $2$

Therefore, it’s a quadratic function

Conclusion:

Hence, $y=3x^2+4x$ is quadratic function.
