which of the following relations is currently a functions but fails the vertical line test when the coordinates are switched? 1. y2 = x - 3 2. y = x 3. y = cosx 4. x2 + y2 = 16

Q: Determine which of the following equations defines y as a function of x. (a) x-y = 16 (b) x-2y = 8

A: x-y2=16 On simplification, we get ⇒y2=x-16⇒y=±x-16 Clearly for each value of x, there are two values…

Q: Identify the function in which y varies directly with x.   x = 5y   x = 5y − 5   x = 5y + 5…

A: the question say that if we change the value of   "x"  then the value of  "y"  will change directly…

Q: List the quadrant or quadrants xy > 0 satisfying condition.

A:

Q: Find the value of y when x=-1      1/6x+3/4y=4

A:

Q: Find the interval in which the following function is positive: 3. -1 1 2 3 6 -1 -2 -3 4)

A:

Q: R(x)= ex-1

A: Domain of a function is the all possible values of x such that f(x) exists finitely. for f(x)…
