What is the domain of the function y = log(x + 3)?

Find the domain of

y = log(x + 3)

Logarithms can only be taken for positive numbers. So you must have

x + 3 > 0

x > – 3 ✔

So the domain of the function is

D = {x ∈ R: x > – 3}

or using the interval notation

D = (– 3, +∞)

I hope this helps. =)

Consider this exponential equation:

ioda

Step-by-step explanation:

F( x ) = 5 (3) ^ x

Y intercept

Let x = 0

f(0) = 5× 3 ^ 0

f(0 = 5 × 1

f(0) = 5

X intercept

let y = o

0 = 5 × 3 ^x

No x intercept/ zero

therefore

Vertical intercept (0; 5)

Alexus [3.1K]

Hey there!

Andrea makes 20% more than Cassidy.

Work:

10 x 0.20 = 2

10 - 2 = 8

So that proves it is 20%.

Hope this helps!
