Question

if p(x)=2+5x then p(2)+p(-2)-p(1)=?​

Answer 1

Step-by-step explanation:

Given,p (x)=2+5x

p (2)=2+5 (2)=2+10=12

p (-2)=2+5 (-2)=2-10=-8

p (1)=2+5 (1)=2+5=7

p (2)+p (-2)-p (1)=12-8-7=12-15=-3

Answer 2

Answer:

p(x)=2+5x

p(2)=2+5(2)

=2+10

=12

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

=2-10

= -8

p(1)=2+5(1)

=2+5

=7

p(2)+p(-2)-p(1) = 12+(-8)-7

=12-8-7

=12-15

= -3
