Answer:

1.-7

2. 5

3. 13

Step-by-step explanation:

1. When x=1, then,

F(1)=(1)(1)-3(1)-5

=1-3-5

=-1-8

=-7

2. When x=-2, then

F(-2)=(-2)(-2)-3(-2)-5

=4+6-5

=10-5

=5

3. When x=-3, then

F(-3)=(-3)(-3)-3(-3)-5

=9+9-5

=18-5

=13

Answer:

1. p(1)= -7

2. p(-2)= 5

3. p(-3)= 13

Step-by-step explanation:

1. p(x)=x²-3x-5

p(1)=(1)²-3(1)-5

p(1)=1-3-5

p(1)= -7

2. p(x)= x²-3x-5

p(-2)= (-2)²-3(-2)-5

p(-2)= 4+6-5

p(-2)= 5

3. p(x)= x²-3x-5

p(-3)= (-3)²-3(-3)-5

p(-3)= 9+9-5

p(-3)= 13
