Answer:
f( -2 ) = 6,
f( -0.5) = 4.5
f(3) = 1
Step-by-step explanation:
To evaluate the function at the given points, we put in the x values and evaluate.
For x = -2 we have
![f(-2)=-(-2)+4_{}](https://img.qammunity.org/2023/formulas/physics/college/6x6rev09s83j4kxpq75w4hoiles8vcrij9.png)
![f(-2)=2+4=6](https://img.qammunity.org/2023/formulas/physics/college/kfxde2hzjr8u91jshlcs7e90j1872w71p0.png)
![\boxed{f(-2)=6}](https://img.qammunity.org/2023/formulas/physics/college/80d1cycu6eddujzqdwsleiwwxmwz9vxbwe.png)
For x = - 0. 5, we have
![f(-0.5)=-(-0.5)+4](https://img.qammunity.org/2023/formulas/physics/college/m3m8d5i9n6wdt5pdi77d8nb512jlppwic3.png)
![\boxed{f\mleft(-0.5\mright)=4.5.}](https://img.qammunity.org/2023/formulas/physics/college/pjzdssm2jf8p9p96rpdnnmbng0imlcgm6g.png)
For x = 3 we have
![f(3)=-3+4](https://img.qammunity.org/2023/formulas/physics/college/31fy52a5cfbcgah6tuyg3s42tcrip7k752.png)
![\boxed{f\mleft(3\mright)=1.}](https://img.qammunity.org/2023/formulas/physics/college/o39ka1hennl9u1gr0fpq6d69jpj2tl11sx.png)
Hence, to summerise:
f( -2 ) = 6,
f( -0.5) = 4.5
f(3) = 1
