Answer:

-1

Step-by-step explanation:

There are things called domain and range.

Domain is all the x values and range is all the y values.

Since in your picture the parabola only seems to be touching -1, that is your domain.

Answer:

The domain is all real numbers.

Step-by-step explanation:

Imagine the arrows extending forever. There is nothing to the left or right to stop them from growing infinitely far apart, and <u>including all numbers</u> in between! The domain is vast!

It may help to think of range like a mountain range with peaks and valleys. A parabola's vertex might be the peak of a mountain or the low spot in the valley.

In the graph shown here, the vertex is at (-1,0) The range can't go any higher. But the arrows point forever to negative infinity. So if the question asked about the range, it would be all numbers less than or equal to 0.

I hope this helps you understand better!

Maximal use of bezels, gradients, and drop shadows make an interface highly user friendly True False
tigry1 [53]
Bezels, gradients, and drop shadows can make an interface user-friendly if used wisely and minimally. If too much, the interface can be distracting. The problem used the term "maximal." This means that the bezels, gradients, and drop shadows are excessively used in an interface. So, the answer to this question is 
FALSE
Using too much image effects can make an interface not user-friendly.<span />

A customer buys a CD for $15 and a video game. The customer pays a total of $42.80 for the two items, which includes 7% sales ta
kari74 [83]

Answer:

1.07 (15 + x) = 42.80

Step-by-step explanation:

Given data

CD= $15

Let the cost of the video game be x

The total cost= 15+x

Hence the equivalent expression is

1.07 (15 + x) = 42.80

open bracket

16.05+1.07x= 42.80

42.80-16.05= 1.07x

26.75=1.07x

x= 26.75/1.07

x= 25

Check

7% tax for CD

=0.07*15

=1.05

total =1.05+15

=$16.05

7% tax for Video game

=0.07* 25

=1.75

total =1.75+25

=$26.75

In all

=26.75+16.05

=$42.8

Jasmine has taken an online boating safety course and is now completing her end-of-course exam. As she answers each question, th
dsp73

Answer:

There are 60 total questions on the course exam.

Step-by-step explanation:

Given that:

Number of questions finished by Jasmine = 12

Percentage shown on the bar = 20%

The total number of questions will be 100%, therefore, 20% of the questions are equal to 12.

Let,

x be the total number of questions on the course exam

20% of x = 12

\frac{20}{100}x=12\\0.2x=12

Dividing both sides by 0.2

\frac{0.2x}{0.2}=\frac{12}{0.2}\\x=60

Hence,

There are 60 total questions on the course exam.
