The negative infinity for the x coordinate states that the graph should move to the bottom and the y coordinate is positive infinity so that the graph goes up

Answer:

option A

Step-by-step explanation:

Domain is the set  of all x values and range the set of all y values where the function is defined.

In the first option we have graph on both  sides of x. we have graph y for all x values . So, domain is (-∞, ∞)

There is no restriction for y. the graph is for all y values

So range is (-∞, ∞)

In the second option, the graph is above y axis so range is [0,∞)

In the third option, we have graph only for positive value of x

so domain is [0,, ∞)

In the fourth option , the graph is above y axis so range is [0,∞)

If using the method of completing the square to solve the quadratic equation x2 + 3x - 17 = 0, which number would have to be add
MatroZZZ [7]

Answer:

Step-by-step explanation:

To solve using completing square, we need to write the equation as x2+3x=17.

The next step is to add a number such that the square can be completed. The number must be equal to (b/2a)^2, so here it will be (3/2)^2 = 9/4

The equation then becomes x2+3x+(9/4)=17+(9/4).

Solving it further will get you the final answer

220 +152 =372 divided by 34 (because they all painted at the same rate)=10.94 sq ft they each painted
