Select the correct answer.
given
d = {x | x is a whole number}
e = {x | x is a perfect square between 49 and 100}
f = {x | x is an even number between 10 and 20}
the expression d ∪ f means (all whole numbers, 64 and 81).
the expression d ∩ f means (16 22 24 18, 12 14 16 18).
the expression d ∩ e means (64 81, all whole numbers).
the expression e ∩ f means (the empty set, all whole numbers).
the expression d ∩ (e ∪ f) means (empty set, 81 64 12 14 16 18).

answer: this doesnt make any sense especially the photo.

step-by-step explanation:

c. 16 units

step-by-step explanation:

mark brainliest and have a great day!

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
