Answer:

Yes

Step-by-step explanation:

A function is a relation for which each value from the set of the first components of the ordered pairs is associated with exactly one value from the set of second components of the ordered pair.

Hope this helps!

Yes because  the definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.  We can write the statement that f is a function from Y to X using the function notation

Answer:

As functions of a true variable, exponential functions are uniquely characterized by the very fact that the expansion rate of such a function (that is, its derivative) is directly proportional to the value of the function.

Step-by-step explanation:

Have a nice day hope this helps.

Find the equation of the line that is perpendicular to y = –3x + 1 and passes though the point (6, 3).
noname [10]

Answer:

A. y=1/3x+1

Step-by-step explanation:

When finding a line that is perpendicular to another line, all you have to do is find the "opposite reciprocal" of the slope. In this case that means writing the slope as the fraction -3/1, and then flipping the fraction over (1/-3) and taking away the negative sign which gets you 1/3 for the slope of your new line. Now, all you have of your new equation is the slope. You need to take your new equation (y=1/3x+b) and plug in the x and y coordinates to that equation, and then solve for the last variable which is b. That solving process goes as follows:

3=1/3*6+b

3=2+b

1=b

now you can replace the b with 1 in your equation to get your final answer of y=1/3x+1
