One thing I want to clarify for you, It's Evaluate, not Avaluate.
Okay so, we want to find the value of 2^3x-1 and we know x = 1.
You didn't really clarify if the expression was or
, so I'll be doing both:
For , we should plug in x to get
and then simplify to get
.
2 to the power of 2 or is equal to 2 * 2 or 4.
The second one, , we should plug in x to get
and then to become
. 2 to the power of 3 or
is 8 and then minus 1 is 7.

model:
profit in year 2017:
Step-by-step explanation:
The sales increased from 2 billion dollars to 146 billion dollars in five years, so to find the increase in billion dollars per year, we just need to divide the increase by the amount of time:
To construct a model for these sales, we can use the year 2003 as the initial point of a linear equation:
the variable y will represent the profit in billion dollars, the variable x will represent our time, so we can use (t - 2003) in its place to represent the number of years since 2003 (t is the year we want to calculate), the constant 'a' will be our rate of 28.8, and the constant 'b' is the inicial value for the year 2003, that is, 2 (billions). So we have:
In the year 2017, we would have:
