7 = 2x + 15
<7
Subtract by 15
-8 = 2x
Divide by 2
-4 = x
<8
8 = 3x
divide by 3
8/3 = x
The data value 2.5 will lie below the second quartile

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. =)
