Answer:

[tex]f(3) =-8[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 2x + 5; x<1[/tex]

[tex]f(x) =-3x + 1; x >1[/tex]

Required

Determine f(3)

f(3) implies that x = 3.

We make use of

[tex]f(x) =-3x + 1[/tex]

Because x >1 (i.e. 3 > 1)

Substitute 3 for x in f(x) =-3x + 1

[tex]f(3) =-3*3 + 1[/tex]

[tex]f(3) =-9 + 1[/tex]

[tex]f(3) =-8[/tex]
