Answer 3

@rock_mit182
can you explain number 5 to me? I took a guess on it, but I'd like to know the correct way to do it.

Answer 4

for the Question 5 we see that when x=0 than the value of y is +5 or -5. Which is the y intercepts.

Thus, the range for any real value of x(domain) will be a number greater than 5 and less than -5. (range)
