Some new school question and answer enquired students to mention what they assume is the most important important factor for a student to do in order to score success. From the numerous comments, one that that stood out was practice. People who were successful do not become successful by being born. They work hard and determination their lives to succeeding. This is how you can attain your goals. These are some question and answer examples that you may make use of to upgrade your knowledge and gain insight that will help you to sustain your school studies.
Which statements are true of functions? Check all that apply. All functions have a dependent variable. All functions have an independent variable. The range of a function includes its domain. A vertical line is an example of a functional relationship. A horizontal line is an example of a functional relationship. Each output value of a function can correspond to only one input value.
The true statemens are:
All function have (at least) a dependent variable. That is why you can write y = f(x), x is the independent variable, while y depends on x values, so y is the independent variable.
All function have and independent variable (explained above).
A horizontal line is an example of a funcitional relationship (because given a value of x, you can always tell the value of y)
The other statements are false:
range of a function includes its domain is false.
Domain are the values that x can take and the range are the values that the function (y) can take. One is not included in the other.
A vertical line is an example of a
functional relationship is false, because you can not tell the value of y for any value of x.
Each output value of a function can correspond
to only one input value is false. An output can be generated by more than one value of x. The horizontal line is an example of that: the same value of y (output) corresponde to any value of x.
They might possibly hopefully assist the student take care of the question by make use of the questions and answer examples. You could actually then have a discussion with your classmate and continue the school learning by studying the problem alogside each other.
