Is it linear or exponential

Answer 1

Explanation

• Linear

Linear is a straight line. You might have heard of Linear Function.

$y = mx + b$

The equation above is slope-intercept form.

• Exponential

Exponential is both increasing graph and decreasing graph depending on the coefficient.

Exponential Equation

$y = {a}^{x} \: \: \: (a > 0) \: \: (a \neq1)$

Exponential Graph increases when a-term is greater or equal to 1.

Exponential Graph decreases when a-term is greater than 0 but less than 1.

From the equation, it is exponential of x-term as an exponent. The equation matches with exponential form.

Answer

• Exponential
