Question

If p(x) = 4 + 3x - x2 + 5x3, find: give the answer below please

(i) p(2)​

Answer 1

Answer:

Step-by-step explanation:

p(-2) = -46

p(x) = 4 + 3x - x² + 5x³

we get p(-2) by substituting -2 for each x in the formula:

 p(-2) = 4 + 3×(-2) - (-2)² + 5×(-2)³

          = 4 - 6 - 4 - 40

          = -46

OR

p(2)= 4+ 3(2) - (2)² + 5(2)³

= 4 + 3x2 - 2x2 + 5(2x2x2)

= 4 + 6 - 4 + 5(8)

= 4 + 2 + 5x8

= 6 + 40

= 46 Ans
