Reflecting the graph of y=cosx across the y axis is the same as not reflecting it at all.
true or false

True

Step-by-step explanation:

The graph of is an even function.

This means that the graph of is symmetric about the y-axis.

If we reflect the graph of about the y-axis, it will fall exactly on its outline.

This makes it behave as if it has not been reflected at all.

In other words, the mapping for reflection about the y-axis is

Since

The graph will retrace its outline.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
