Functions are not always a straight line, no. a parabola is a function, and it forms a "U" shape. a straight line is called a LINEAR function, but there are many non-linear functions.

y = x does represent a function. while it doesn't look like it, this equation is still in slope-intercept, y = mx + b, form. the slope is just 1 and the y-intercept is 0, so what's left is the equation y = x. the definition of a function requires an output for every input, and this equation still works. try plugging in 1 for x:

y = (1)
y = 1

so when your input is 1, your output is also 1. look at the graph of y = x and you'll understand why this works. furthermore, while looking at the graph, you can double check that this is a function with the vertical line test (which makes sure that x values aren't repeated).

Solve five and three sixths minus two and one third.
CaHeK987 [17]

Answer:

3 3/18

Step-by-step explanation:

5 3/6-2 1/3

We first need to turn our mixed numbers into fractions by multiplying the while number by the denominator, then adding the numerator. When we do this, 5 3/6 turns into 33/6 and 2 1/3 turns into 7/3. Now we have this:

33/6-7/3

Now we need to find the Least common multiple of the denominators in order to find our common denominator, which in this case is 6. 33/6 already has a denominator of 6, so we do not need to do anything to it. To give a denominator of 6 to 7/3, however, we must multiply by 2, giving us this:

33/6-14/6

Now we can subtract the numerators.

19/6

To turn this back into a mixed number, we divide 19 by 6, which gives us 3 with a remainder of 1. Therefore, our answer is 3 1/6. This is an equivalent fraction to the fourth answer, 3 3/18.
