Answer:
It would be T.
Step-by-step explanation:
My reasoning is because...what considers a function to be a function is ONE INPUT (X-VALUE(S)) TO HAVE ONE OUTPUT (Y-VALUE(S)). When you look at table T it has two 3's which essentially is just one 3 but it has TWO DIFFERENT OUTPUTS, that is not considered to be a function. Hope this helps :)
I will do it and send it to you in 12 hours
Note: Since the symbols for greatest integer function (GIF) and least integer function (LIF) are not given, I will be using the words GIF and LIF in the solution
GIF x means largest integer less than or equal to x, and LIF x means least integer greater than or equal to x.
We need to determine which expressions are equal
Option 1: GIF 4.9 and LIF 3.1
GIF 4.9 = 3
LIF 3.1 = 4
Hence GIF 4.9 ≠ LIF 3.1
Option 2: GIF 15.2 and GIF 14.8
GIF 15.2 = 15
GIF 14.8 = 14
Hence, GIF 15.2 ≠ GIF 14.8
Option 3: GIF -6 and LIF -6
GIF -6 = -6
LIF -6 = -6
Hence, GIF -6 = LIF -6
Option 4: LIF -3.2 and LIF -2.6
LIF -3.2 = -2
LIF -2.6 = -1
Hence, LIF -3.2 ≠ LIF -2.6
Hence, only in Option C the pair of expressions are equal.
<span><u>5x∛69 = 6x√59</u></span>
Subtract 6x√59 from each side:
5x∛69 - 6x√59 = 0
Factor the left side:
x (<span>5∛69 - 6√59) = 0
Divide each side by (</span><span>5∛69 - 6√59) :
<u>x = 0</u>
