MEDALS??? What is the range of y = sinx in the interval - π ≤ x ≤ 0? -1 ≤ y ≤ 1 -1 ≤ y ≤ 0 0 ≤ y ≤ 1 y ≤ 1

    do you know what range is?

    And also, do you know what the graph of a sin function looks like?

    wait, what is it that you don't know? range? the graph of a sin function? or both?

    okay, so the range basically describes all the y values a particular function can possibly have, so for e.g. |dw:1443789985087:dw| the range of this function would be -3 ≤ y ≤5 do you see what I mean?

    So for your particular question, you need to be familiar with the sin function which looks something like this |dw:1443790151790:dw|

    now in this particular question, we are asked for the range, for when the domain is -π ≤x ≤0 which is in this section |dw:1443790370016:dw|

    so we have to apply our knowledge of what a range is, in order to be able to recognise the range for the section above, so what do you think the range would be in this case?
