Lesson 2.4 - sketching graphs of functions

Sketch a linear graph when given key features
Sketch a nonlinear graph when given key features

Draw

The y-intercept is 1. The function is positive for all values of x. The function is decreasing for x < -1. The function is increasing for x > 1. As $x\rightarrow\infty$ , $f\left(x\right)\rightarrow\infty$ and as $x\rightarrow-\infty$ , $f\left(x\right)\rightarrow\infty$ .
