What is the domain of the function y = 2e^x graphed below

ANSWER

The domain is all real numbers

EXPLANATION

The domain of a function refers to all values of

that make the function defined.

The function given to us is


The above function is an exponential function.

All exponential functions are continuous functions.

This means the function is defined everywhere. There is no break in the graph of this function.

Therefore the domain is the entire real numbers.

In interval form we write it as



We can also write the domain as,

Ithink ghe answer to this question is b just trying to others

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
