Can someone tell me the domin and range of graph 18? you can use the infinity sign

We see that if you restrict the domain of x+4 (-∞,0] it will have a maximum at 0 (it's strictly increasing), so it will have a maximum at (0,4). We see that 4-x^2 also has a maximum at (0,4), which we know because the vertex of a quadratic is always its max/min based on the leading coefficient, so and the vertex of this quadratic is (0,4), and since its leading coefficient is negative, it's the maximum. That means since both of these functions decrease without bound and have a maximum of (0,4), the range is: (-∞,4).

The domain here is easier. x+4 an 4-x^2 are both defined at every point. We also see that the x value where there would be a discontinuity at, x=0, has a closed circle which means its defined at that point. That means our domain is just: (-∞,∞)

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
