Domain: [-2, 2]

Range: [-3, 3]

Step-by-step explanation:

Domain (x) is the left and right. Range (y) is the up and down.

It's a bracket if it is included, meaning, there is no gap or hole.

If it weren't included, it'd be a parentheses instead "( )". For example, if there was an open circle.

It would go to -infinty or +infinity if it were to go on forever, and that would be in parentheses.

EX: (-∞,∞) or (-∞, 8]

You can mix and match the brackets and parentheses depending on whether or not it touches/includes the number, like I've mentioned.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
