Answer:

p(5) =  - 5 \\ p(0) = 5 \\ p( -  \frac{1}{2} ) = 6

Step-by-step explanation:

p(x) =  - 2x + 5

We substitute x = 5,0 and - 1/2 in the equation.

p(5) =  - 2(5) + 5 \\ p(5) =  - 10 + 5 \\ p(5) =  - 5

p(0) =  - 2(0) + 5 \\ p(0) = 0 + 5  \\ p(0) = 5

p( -  \frac{1}{2} ) =  - 2( -  \frac{1}{2} ) + 5 \\ p( -  \frac{1}{2} ) = 1 + 5 \\ p( -  \frac{1}{2} ) = 6
