Answer:

[tex]f(0)=4[/tex]

[tex]f(6) = 8[/tex]

Step-by-step explanation:

Given

The piece wise function

Solving (a): f(0)

To solve for f(0), we make use of:

[tex]f(x) = x + 4[/tex]

Because: the inequality [tex]x < 5[/tex] satisfies x = 0

i.e: [tex]0 < 5[/tex]

So, we have:

[tex]f(x) = x + 4[/tex]

[tex]f(0)=0 + 4[/tex]

[tex]f(0)=4[/tex]

Solving (b): f(6)

To solve for f(6), we make use of:

[tex]f(x) = 8[/tex]

Because: the inequality [tex]5 \le x < 7[/tex] satisfies x = 6

i.e: [tex]5 \le 6 < 7[/tex]

So, we have:

[tex]f(6) = 8[/tex]
