Which expression is equivalent to (cos x)(tan(–x))?
Naya [18.7K]
The tan(-x) is the same thing as -tan(x).  The tangent function is also the same thing as sin(x)/cos(x), right? So let's rewrite that tan in terms of sin and cos:
[cos(x)][tan(-x)] is the same as [cos(x)][ -\frac{sin(x)}{cos(x)}]
We can now cancel out the cos(x), which leaves us only with -sin(x) remaining. So your answer is A.

Arrange these functions from the greatest to the least value based on the average rate of change in the specific interval
oee [108]
The average r. of c. of a function f(x) on an interval [a,b] is:

  f(b) - f(a)
--------------
    b-a

You'll need to apply this to all four of the given functions.

First function:  f(x) = x^2 + 3x
a= -2; b= 3

Then the ave. r. of c. for this function on this interval is:

    18  - (-2)            20
------------------ = ---------- = 4.  y increases by 4 for every unit increase in x.
      3-(-2)                5

Do the same thing for the other 3 functions.

Then arrange your four results in descending order (greatest to least).

What is the quadratic domain of y=x squared
statuscvo [17]

domain is the numbes you are allowed to use for x

what I usually do is just find the numbers that aren't allowed in the domain. such numbers are numbers that cause a division by 0 or a squaer root of a negative number

given y=x^2, there are no numbers that you can use for x that will cause a division by 0 or a square root of a negative number


so domain is all real numbers or D={x | -∞<x<∞}
