Is this a question on your test or something? I know trying out every number and letter would be difficult. There is a way to solve these types of problems. Ask your math teacher, or someone that knows this or has taught this.
Y = sin(x^2)
Use the chain rule.
We want dy/dx.
dy/dx = cos(x^2)*2x
dy/dx = 2xcos(x^2)
Did you follow?
Answer:
C.Yes, because every x-value corresponds to exactly one y-value.
Step-by-step explanation:
A function is a relation in which each element of the domain (x) is mapped to one element of the range (y). This means that no x can be mapped to more than one y; basically it means that no x can repeat.
In this table, no x repeats; each x is mapped to only 1 y. This means that it is a function.
Price of the collar = $12.00
Sales Tax = 10% x $12 = 0.1 x 12 = $1.20
Total Cost = $12.00 + $1.20 = $13.20
Answer: $13.20
The equation would be y+y1=slope(x+x1) which means it will be y+-21=slope(x+7)
I believe that is right. I don't know what the slope is though. Welp.
