9 and 15
Step-by-step explanation:
lowest common multiple 45
9, 18, 27, 36, 45, 54, 63, 72, 81, 90
15, 30, 45
HCF
3 X 3 = 9
3 X 5 = 15
3 is hcf
Answer:
-1/9, 1/9
Step-by-step explanation:
If we represent this with an equation, we get 3 + |-9x| = 4. Subtract 3 from both sides and we get |-9x| = 1. There are two solutions to this, 1/9 and -1/9, since they both multiply to a number whose absolute value is 1. (-9 * 1/9 = -1, 9 * 1/9 = 1. -1 has an absolute value of 1.)
An even function is a function where positive and negative values of x give you the same result.
Where f(2) = f(-2) and f(3) = f(-3)
To formally check it, you need to evaluate f(-x) and see if you get the original function back.
Graphically, an even function is symmetrical over the y-axis.
The only graph here that does all of that is f(x) = |x|
