Leo wants to use s(x) = -x
2
+ 10x - 24 to answer a question. The goal is to identify the constant term as s(0). Which move is best?
A
Rewrite to s(x) = -(x - 5)
2
+ 1, because the vertex gives every x-intercept immediately.
B
Make a table first, because equivalent forms do not help with this question.
C
Rewrite to s(x) = -(x - 4)(x - 6), because the factors make the constant term easiest to read.
D
Keep s(x) = -x
2
+ 10x - 24, because this form already shows s(0) through the constant term.
