Question

Please help! I'm getting timed.

Answer 1

Hi there! The answer is A.


`t = 2(s + 2)`
To get a proper idea of the type of function this formula represents we work out the parenthesis.

Working out the parenthesis can for instance be done using rainbow technique.

`t = 2s + 4`

We can now see sinilarities between this function an the general function of a line in slope intercept form

`y = mx + n`

The function t therefore describes a line with slope 2 and y-intercept 4. Therefore the answer is A.
