What is the domain of F?

Given a function f , the set x values (inputs) is the domain of f , and the set y values ( outputs ) is the range of f . The domain of a function f is all of the values for which the function is defined. For instance, 1x is not defined when x=0 . Also, √x is not defined when x is negative.

Step-by-step explanation:

option A.

Step-by-step explanation:

if the blue dots represent the function it's domain will be the values of x for which a blue dot is raised.

The "points" have coordinates:

Now, the abscissa, I.e., the x coordinate of a point represents its domain, while the ordinate, I. e., the y coordinate represents its range.

Therefore,

Domain:

{0, -6, 2, 4, 7}

Range:

{4, 1, -5, 3}

That is, option A!

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
