Which function results after applying the sequence of transformations to

Ad libitum [116K]

Answer:

The resulting function after the sequence of transformations is $f(x)=3(x+2)^5+1$

Step-by-step explanation:

Given a function f(x)

the function a*f(x) will be a vertical stretch of factor a, given a > 1
the function f(x) + b will be the translated function vertically up b units
the function f(x+c) will be horizontally translated function of the original by c units left

Remembering these points, we can apply the rules to $x^5$ .

Strech vertically by 3 would be $3x^5$
translate up 1 unit would be $3x^{5}+1$
translate left 2 units would make it $3(x+2)^5+1$

Hence the new function would be $3(x+2)^5+1$

Answer:

Step-by-step explanation:

We have to substitute x with 2 and y with 4

when the sign of a operation is not expressed it means that the operation is a

multiplication

So we have

3*2 + 2*(4)^2

6 + 2*(16)

6 + 32

What is the input of arccos

suter [353]

Answer:

It returns the angle whose cosine is a given number.

Step-by-step explanation:

For every trigonometry function, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arccos button may be labeled arccos, or sometimes cos-1.) So the inverse of cos is arccos etc. When we see "arccos x", we understand it as "the angle whose cosine is x"

cos30 = 0.866 Means: The cosine of 30 degrees is 0.866

arccos 0.866 = 30 Means: The angle whose cosine is 0.866 is 30 degrees.

Use arccos when you know the cosine of an angle and want to know the actual angle.
