Analyze the following table of values.<br><br> y=1/2x<br> y=1/2^x2+4<br> y=4^x2+1/2<br> y=4(1/2)x
Fittoniya [83]

The table models an exponential relationship, and the equation of the table is y = 4(1/2)^x

<h3>How to analyze the table of values?</h3>

The table of values is given as:

x  0   1    2   3    4

y  4   2    1   1/2  1/4

The above table shows an exponential model

An exponential model is represented as:

y = ab^x

When x = 0 and y = 4, we have

ab^0 = 4

Evaluate

a = 4

When x = 1 and y = 2, we have

ab^1  = 2

Evaluate

ab  = 2

Substitute 4 for a

4b  = 2

Divide both sides by 4

b = 1/2

Substitute 4 for a and 1/2 for b in y = ab^x

y = 4(1/2)^x

Hence, the equation of the table is y = 4(1/2)^x

Here's a question for the day, it's simple but it needs explaining.

It is used to see if a graph represents a function because if there is 2 dots or intersecting lines within the other lines then it is not a function. if there is only one line or dot, then yes, it is a function. hope i explained it well.
