Question

p(x) = 2X^2 - 7x +1 then evaluate p(3) + p(1/2) + p(-2)

Answer 1

(2*9 - 21 + 1) + (2*(1/4) - 7/2 + 1) + (8 + 14 + 1)
= (18 - 21 + 1) + (1/2 - 7/2 + 1) + 23
= - 2 - 2 + 23
= 19

Answer 2

Answer:

19

Step-by-step explanation:

p(3)= 2*9 - 21 + 1

p(1/2)= (2*(1/4) - 7/2 + 1)

p(-2)= (8 + 14 + 1)

now ,p(3) + p(1/2) + p(-2)=

= (18 - 21 + 1) + (1/2 - 7/2 + 1) + 23

= - 2 - 2 + 23

= 19
