Question

If `2x + 14` for `-7<=x<-5, 4` for `-5<=x<1` and `3/2x + 5/2` for `x>=1`, how do you find `f(-6)`?

Answer 1

2

Explanation:

From the question:
`f(x)=2x+14` for `-7lex<-5`
`g(x)=4` for `-5lex<1`
`h(x)=3/2x+5/2` for `1lex`

When x=-6, only `f(x)` is applicable.

Hence,
`f(-6)`
`=2(-6)+14`
`=2`
