Please help me, this is a test. i will give brainliest for answering all of this. i know it’s a lot but i need help. 1. Graphs of two trigonometric functions are shown below.
- what is the period of the solid graph
- what is the period of the dotted graph
- the solid graph is one of the six trigonometric functions. which is is? how do you know?
- the dotted graph is a transformation of the solid graph. it shows a vertical stretch and a horizontal compression. what is the vertical stretch factor of the dotted graph?
- generate the function that produces the dotted graph
- the function that produces the solid graph is a reciprocal function for another trigonometric function. use the y-intercept of the solid graph to identify this reciprocal function.

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
