The completion of the table for this function, y = 2ˣ is as follows:
x y = 2ˣ
-2 1/4
-1 1/2
0 1
1 2
2 4
A function is an expression, rule, or law that depicts the relationship between two variables, the independent (x) and the dependent (y) variables.
The following are types of functions in mathematics:
- Linear
- Power
- Quadratic
- Polynomial
- Rational
- Exponential
- Logarithmic
- Sinusoidal.
Given:
y = 2ˣ
Therefore, we can determine y when x is -2, -1, 0, 1, and 2 as follows:
y = 2^-2 = 0.25 or 1/4
y =2^-1 = 0.5 or 1/2
y = 2^0 = 1
y = 2^1 = 2
y = 2^2 = 4
Thus, we have completed the table for the function, y = 2ˣ.
