Answer & Step-by-step explanation:
When using piecewise functions, the intervals represents what function will be used when given a certain number. So, let's begin.
For f(-3), we will use the first function because -3 is less than -1.
<em>f(-3) = 7/2 + 2(-3)</em>
<em>f(-3) = 7/2 - 6</em>
f(-3) = -5/2
For f(-1), we will use the first function again because -1 equals -1.
<em>f(-1) = 7/2 + 2(-1)</em>
<em>f(-1) = 7/2 - 2</em>
f(-1) = 3/2
For f(3), we will use the last function because 3 equals 3.
<em>f(3) = 1/4(3)</em>
f(3) = 3/4
Answer:
The factored form of the equation is (x+4)(x-6)=0.
Step-by-step explanation:
Because (x-4)(x+2)=x^2-4x+2x-8=16,
so that means x^2-2x-8=16,
move 16 to the other side,
you get x^2-2x-8-16=0,
simplify,
you get x^2-2x-24=0,
which satisfies (x+4)(x-6)=0 when factored out.
Because (x+4)(x-6)=x^2+4x-6x-24=x^2-2x-24=0.
Answer:
f. the sequence goes by the half of the previous number.
= 16, 8, 4, 2, 1, 1/2, 1/4, 1/8...
g. the sequence goes by adding the consecutive odd number added to the previous number.
first number= 3.
second number= 3+3
= 6
third number= 6+5
= 11
fourth number= 11+7
= 18
fifth number= 18+9
= 27
sixth number= 27+11
= 38
seventh number= 38+13
= 51, etc.
= 3, 6, 11, 18, 27, 38, 51...
Answer:
False
Step-by-step explanation:
A regular sided polygon means all the sides have the same length and all angles the same size. This polygon has 2 sides the same length, not 3 sides the same length, so it cannot be regular.
