If px = 2x^3 + 3x^2 + 4x, then what is p(1)?

To find p(1), we start by substituting x with 1 in the polynomial px.

Let’s plug in the value:

px = 2(1)^3 + 3(1)^2 + 4(1)

This simplifies to:

px = 2(1) + 3(1) + 4(1)

Now, calculating each term:

px = 2 + 3 + 4

Adding these values together gives:

px = 9

Therefore, p(1) equals 9.

In summary, by substituting x with 1 in the polynomial, we found that p(1) equals 9 through straightforward arithmetic.
