Answer:
See attached image for the graph of the function
Step-by-step explanation:
Notice that this is the product of a power function (
) times the trigonometric and periodic function cos(x). So the zeros (crossings of the x axis will be driven by the values at which they independently give zero. That is the roots of the power function (only x=0) and the many roots of the cos function: 
, and their nagetiva values.
Notice that the blue curve in the graph represents the original function f(x), with its appropriate zeros (crossings of the x-axis), while the orange trace is that of "-f(x)". Of course for both the zeroes will be the same, while the rest of the curves will be the reflection over the x-axis since one is the negative of the other.
Using translation concepts, the images of the points are given as follows:
25. (4,3).
26. (3,1).
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
The rule for a reflection across y = x is given by:
(x,y) -> (y,x).
Hence, in item 25:
The image of (3,4) is (4,3).
The rule for a reflection across y = -x is given by:
(x,y) -> (y,-x).
Hence, in item 26:
The image of (-1,3) is (3,1).
