Answer:

a.[tex]f(-1)=2[/tex]

b.[tex]f(3)=6[/tex]

c. [tex]f(x-1)=x+2[/tex]

Step-by-step explanation:

We are given that [tex]f(x)=x+1+2[/tex]

a.We have to find the value of f(-1)

Substitute the value of x in the given function

Then, we get

[tex]f(-1)=-1+1+2=2[/tex]

[tex]f(-1)=2[/tex]

b.We have to find the value of f(3)

Substitute x=3 then we get

[tex]f(3)=3+1+2=6[/tex]

[tex]f(3)=6[/tex]

c.We have to find the value of f(x-1)

Replace x by x-1 then we get

[tex]f(x-1)=x-1+1+2=x+2[/tex]

Hence, [tex]f(x-1)=x+2[/tex]
