The highest power is 2.
Explanation:
Because x has a maximum power of 2, there will be 2 answers. if it were 3, there could be up to 3 answers, etc.
While solving this problem, you gather all terms on one side so the equation looks like
x
2
−
81
+
17
=
0
x
2
−
64
=
0
then factor
(
x
−
8
)
(
x
+
8
)
=
0
then, because any number times 0 equals 0, we know that one of the two parts in the parenthesis must be equal to 0, so
x
−
8
=
0
or
x
+
8
=
0
and so the two answers
x
=
8
,
−
8
come to be.
Answer:
yes, because it does not have a constant rate of change
Answer:
f(- 1) = - 5
Step-by-step explanation:
f( - 1) has x = - 1 in the interval - 5 < x ≤ 0 , thus
f(x) = | - 3x + 2 | - 10 , so
f(- 1) = | - 3(- 1) + 2 | - 10 = | 3 + 2 | - 10 = | 5| - 10 = 5 - 10 = - 5
