1. [pic]
y = sin x
If we shift the function -2 units vertically and 3 units to the right, the translated function would be:
• y -2 = sinx - 3
• y - 3 = sinx + 2
• y= sin (x - 3) - 2
• y - 2 = sin (x - 3)
• None of the above.
2. [pic]
Necessary, but not sufficient condition fora function f(x) to be continuous at xo is:
• The function has to be defined at xo : f(xo) = yo
• The derivative must exist at x0.
