Question

P(x) = x5 - 5x^3 + 2x^2 - x + 3. Find P(2).
A. 0
B. 1
C. 3
D. 7

Answer 1

to find P(2), just sub in the number 2 wherever you see an x. Like this:\[P(x)=x ^{5}-5x ^{3}+2x ^{2}-x+3\]\[P(2)=(2)^{5}-5(2)^{3}+2(2)^{2}-(2)+3\]

Answer 2

sub from 2?

Answer 3

Put a 2 in for the x in the expression to evaluate the expression for x = 2.
