Answer:
The answer would be A
Step-by-step explanation:
consider the following image
Answer: Hello there!
we have the function f(x) = IxI/x
Then this function can be piecewise writen as:
f(x) = 1 if x > 0
f(x) = -1 if x < 0
because:
suposse that n is a number greater than 0, then:
f(n) = InI/n = n/n = 1
and this is independent of the number n, so for all the positive values of x, we have f(x) = 1
and
f(-n) = I-nI/(-n) = n/(-n) = -1
and again, this does not depend on the value of n, so for all the negative values of x, we have f(x) = -1.
On the other hand, the Heaviside function is defined as:
H(x) = 1 if x>0
H(x) = 0 if x<0
Then the difference is that, when the Heaviside function takes the value of 0 for negative values of x, our function f(x) takes the value of -1 for negative values of x.
Answer:

Step-by-step explanation:
Given the function:

To find:
The value of
= ?
Solution:
means the values of
as:

Let us put the given values in the given function and let us solve for it:

Therefore, the answer is:

Answer:
The other coordinate is (-6,19)
Step-by-step explanation:

(4,-7)
(x,y)
[(4+x)/2 , (-7+y)/2] = (-1,6)
(4 + x)/2 = -1
4 + x = -2
× = -6
(-7 + y)/2 = 6
-7 + y = 12
y = 19
