Estimate the difference between 206 and 167

The difference means we want to how much is one number greater or less than the other.
To estimate the difference we will simply subtract the smaller number from the larger one.

The given numbers are: 206 and 167
It is obvious that 167 is less than 206. Therefore, we will subtract the 167 from the 206.

The difference between the two numbers is:
206 - 167 = 39

Ibelieve a is the correct answer because 3 is the y-intercept you can see it from the graph. so from here the answers could only be a and c. they are differently at the sign.substitute x with 1so the equation for a is 3*(1.4)^x3*(1.4)^1 = 4.2look back at the graph it is true that when x= 1 y= 4.2if you use equation from c. when x= 1 then y will be negative number which is falseso correct answer is a
