Answer:
f( -2 ) = 6,
f( -0.5) = 4.5
f(3) = 1
Explanation:
To evaluate the function at the given points, we put in the x values and evaluate.
For x = -2 we have
[tex]f(-2)=-(-2)+4_{}[/tex][tex]f(-2)=2+4=6[/tex][tex]\boxed{f(-2)=6}[/tex]For x = - 0. 5, we have
[tex]f(-0.5)=-(-0.5)+4[/tex][tex]\boxed{f\mleft(-0.5\mright)=4.5.}[/tex]For x = 3 we have
[tex]f(3)=-3+4[/tex][tex]\boxed{f\mleft(3\mright)=1.}[/tex]Hence, to summerise:
f( -2 ) = 6,
f( -0.5) = 4.5
f(3) = 1
