Answer: 2: an equation in the form y = mx + b

1. An x/y table may have two entries with the same x; not a function in that case.

2. That's a line with a slope; for each x there's a single y, definitely a function

3. Ordered pairs -- like the table, the same x with different ys is possible, which wouldn't be a function.

4. List of numbers -- a list isn't a function, at least not without more context

If h(x)= 3x+5 and h(a) =27, then what is the value of a ?

Usimov [2.4K]

h(x) = 3x + 5

h(a) = 27

We can write this as 3a + 5 = 27

Now, we just need to solve for a.

Subtract 5 from both sides

3a = 22

Divide 3 from both sides.

a = 7.33

Now, let's plug 7.33 back into the original equation.

3 * 7.33 + 5 = 27

22 + 5 = 27

27 = 27 √ this is correct
