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.
