Question

If p(x)=2+5x then find p(2)+(p-2)-p(1) '​

Answer 1

Answer:

The value is 7

Step-by-step explanation:

p(x)=2+5x

p(2)

put x = 2

p(2) = 2 + 5(2)

= 2 + 10

= 12

p(-2)

put x = -2

p(-2) = 2 +  5(-2)

= 2 - 10

= -8

p(1)

put x = 1

p(1) = 2 - 5(1)

= 2 - 5

= -3

Now,

p(2)+p(-2)-p(1)

= 12 + (-8) - (-3)

= 12 - 8 + 3

= 7
