Consider the function y = 2cos(-x)-4. what effect does "-x" have on the basic graph?
a)flip over the vertical axis
b)horizontal shift left 1
c)vertical shift down 1
d)flip over horizontal axis

A)

But really there is no effect since cos(-x)=cos(x).

Step-by-step explanation:

Cosine is an even function.

Even functions are symmetric about the y-axis.

So really for cosine; cos(-x) has no change to cos(x) since they are equal.

But if you keep in mind that cosine is symmetric about the y-axis, then it has been reflected over the y-axis; this is the vertical axis.

A)

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
