18) The degree of P(x) = (x-1)(x+2)(x+3)(2x-5) is

4
3
2
1

degree 4

Step-by-step explanation:

The degree of a polynomial is determined by the term with the largest exponent for the polynomial in standard form

Given

P(x) = (x - 1)(x + 2)(x + 3)(2x - 5)

We need only consider the product of the leading terms in each factor, that is

x(x)(x)(2x) = 2 ← is the leading term in the expansion of the factors

with exponent 4

Thus polynomial is of degree 4

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
