Question

Find p(-2) if p(x) = 3x4 + 3x3 + 7x - 10.

a. -10

b. 0

c. 14

d. 46

Answer 1

I am assuming the equation is p(x) = 3x^4 + 3x^3 + 7x - 10

(the "^" indicating an exponent)

Assign the function:

3(-2)^4 + 3(-2)^3 + 7(-2) - 10

From here, solve as you would a normal equation:

3(16) + 3(-8) + 7(-2) - 10

48 - 24 - 14 - 10

  \   /

   24     - 14 - 10

     \       /

         10     - 10

           \        /

            [  0  ]

So the answer is:

b. 0

Answer 2

in this problem, you take the negative two and plug it in for x

= 3(-2)^4 + 3(-2)^3 +7(-2) -10

= 48 + (-24) + (-14) -10

= 0

the answer is b. 0
