Question

10. f(x) = 2x+5 if x < 4 1x² + 3x if x 24 LX D = R =

Answer 1

Answer:
`\begin{gathered} D=(-\infty,\infty) \\ \\ R=(-\infty,-3)\cup\lbrack-(9)/(4),\infty) \end{gathered}`

Step-by-step explanation:

The domain of the given piecewise function are all the values that x can take.

These are:

x < -4 and

`x\ge-4`

It can be written as:

`(-\infty,\infty)`

The range is:

`(-\infty,-3)\cup\lbrack-(9)/(4),\infty)`
