In drastic need of help! Find an appropriate viewing window for the function, using given x-values.
y=x^2 +25, for x-values between -5 and 5.
Choose the most appropriate viewing window boundaries for the function.
a) [-5,5] by [22,50]      b) [-5,5] by [0,50]
c) [-5,5] by [0,25]        d) [-5,5] by [-10,10]

|dw:1346519788220:dw|So y varies from 25 to 50. Hence the window is [x1,x2] by [y1,y2] where it is given that x1= -5, x2= 5 and y1 is the minimum value of y (=25) for this range and y2 is the maximum value of y (=50).
