Answer:
The distance is 4.
Step-by-step explanation:
The shortest distance from the point (4,2) to the line y=-2, in this case, would be a straight line perpendicular to y=-2.
For each and every value of "x" on the line, y = -2. The shortest distance occurs at y(4) = - 2.
At this point the distance is:

The distance is 4.
<u>Answer:</u>
The range of the function y = 2cos x is -2 <y < 2 .
<u>Step-by-step explanation:</u>
We know that cos (0) = 1 and cos (π) = - 1 are the two extreme values which cos x assume when x ∈ R and it is also that cos (x) is a continuous periodic function with period 2π when x ∈ R ,
since ,
cos (x + 2π) = cos x
So, the range of the function y = 2cos x is -2 <y < 2 .
2x^2 - quadratic - monomial
-2 - constant - monomial
3x - 9 - linear - binomial
-3x^2 - 6x + 9 - quadratic - trinomial
Hope this isn't too confusing
If it is a triangle h is height and b is base.
