Question

Find the value of p(2) + P(-2)
where p(x) = 3x3 - 4x2-7​

Answer 1

Answer:

-46

Step-by-step explanation:

p(x) = 3x³ - 4x² - 7

so, p(x=2) or p(2) = 3(2)³ - 4(2)² - 7 = 1

and p(-2)= 3(-2)³ - 4(-2)² - 7 = - 47

so, p(2) + p(-2) = - 46

Answer 2

Step-by-step explanation:

p(X)= 3*X^3 - 4X^2 - 7

p(2)= 3*(2)^3 - 4 * (2)^2 - 7

p(2)= 24 - 16 - 7

p(2) = 1

p(-2) = 3*(-2)^3 - 4 * (-2)^2 - 7

p(-2) = -24 - 16 -7

p(-2) = -47

so,

p(2) + p (-2) = 1 + (-47)

p(2) + p(-2) = -46
