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. =)
$72 To find out how much the sweater is without 20% off, you need to do this formula:
$60 x 20%
The answer is $12.
So, 20% of $60 is $12.
Now, you need to add 60 and 12 together to get the original sale price.
60 + 12
The answer is 72.
So the original price for the sweater is <span>72 dollars.</span>
So first off the equation we are solving is f(x) + g(x). So i want to plug in those equations first off. The new equation I get should be 3x-2 + 6 -4x. I then simplify this to -x+4 or 4-x.
I think 7 mi is the answer
