Question

What’s the domain and range for f(t)=90-52ln(1+t)

Answer 1

Answer:

Domain: (-1, ∞)

Range: (-∞, ∞)

Step-by-step explanation:

DOMAIN:

In logarithmic functions, inside the parenthesis of the logarithm has to be >0. This is because you cannot make a positive number negative with exponents

Our equation

... $52ln(1+x)\\1+x>0\\x>-1$

Range:

The range of logarithmic equations is (-∞, ∞).

This is because, as $(1+x)$ approaches 0, the natural log of numbers smaller than $e$ become more and more negative. The limit of the function as $(1+x)$ is infinity
