Question

what is the range of this exponential function?1. all real numbers 2. { y | y < -5 }3. { y | y > -5 }4. { y | y ≥ -5 }5. { y | y ≤ -5}

Answer 1

Answer:

{ y | y ≥ -5 }

Explanation:

The rangle of a function are the values of the function on the y axis. From the graph given, the range of the function in set notation [-5, infinity).

This means that the value of the function are values of y that are greater than and equal to 5.

Hence the required set is { y | y ≥ -5 }
