Question

Which function describes this table of values?

Answer 1

Answer:

$y = \frac{1}{2}x +2$

Step-by-step explanation:

From the table of function given, you would observe that if you subtract 2 from half of the x-variable values, you'd get the y-variable values.

For example, half of -8 = -4. If you add 2 to -4, you'd get: -4 + 2 = -2. Same applies to other x-values on the table.

Thus, an expression for the function represented by the table values can be written as,

$y = \frac{1}{2}x +2$
