Math Problem Statement

consider the polynomial functionsp given by p(x) = 7x to the 3rd power - 2x to the second power +3x+10 Evluate the function at x=3

Solution

The given polynomial function is:

p(x)=7x32x2+3x+10p(x) = 7x^3 - 2x^2 + 3x + 10

We need to evaluate the function at x=3x = 3. Substituting 33 into the function:

p(3)=7(3)32(3)2+3(3)+10p(3) = 7(3)^3 - 2(3)^2 + 3(3) + 10

Now, calculating each term:

p(3)=7(27)2(9)+3(3)+10p(3) = 7(27) - 2(9) + 3(3) + 10

p(3)=18918+9+10p(3) = 189 - 18 + 9 + 10

p(3)=190p(3) = 190

Thus, p(3)=190p(3) = 190.
