I dont get how to work this one out give me a secod
To find range, you must find the largest number in your data, and subtract it by the smallest number in your data.
In this case...
the Largest (20) - smallest (0) = Range
the only 2 possible answers are 2 and -2 .But the answer is y=2 because x is positive
Y= x^2-58
X^2-58=0
X^2=58
X= sqrt of 58
X= 7.6
Y= x^2+13
X^2+13=0
X^2=-13
Get sq rt of 13 the negative becomes i
X= 3.6i
