Question

What are the domain and range of the exponential decay function?

A) Domain: X < 3 Range: Y > 3
B) Domain: All real numbers; Range: y > 3
C) Domain: All real numbers; Range: All real numbers
D) Domain x > 3; Range: All real numbers

Answer 1

B) Domain: All real numbers; Range: y > 3

Explanation:

I. x can be any value in real number

but if you look at the graph, the y is near 3 but not 3

So y is more than 3 and x is all real number

When x is domain and y is renge.

That makes domain is real number and renge is more than 3.

Hope that help :)
