Question

For what values of x is f(x) =-2x - 3 increasing? For whatvalues of x is it decreasing?

Answer 1

Given:

`f(x)=-2x-3`

Differentiate with respect to 'x'

`f^(\prime)(x)=-2`
`f^(\prime)(x)<0`

Therefore the function is decreasing.

`\text{The fuction decreasing for the x values (-}\infty,\infty)`
