Question

is the function $y = 10^x - 9$ linear or nonlinear? linear nonlinear

Explanation:

Step1: Recall linear function form

A linear function has the form \( y = mx + b \), where \( m \) and \( b \) are constants, and the variable \( x \) is to the first power.

Step2: Analyze given function

The function \( y = 10^x - 9 \) has \( x \) in the exponent (it's an exponential function), not to the first power. So it doesn't match the linear function form.

Answer:

nonlinear
