Question
Answer True or False to each of the following statements.
a) The function f(x)
4
is continuous at x= 2.
x - 2
b) The instantaneous rate of change of a function at a point is represented graphically as the slope of the
line tangent to the curve at that point.
c) The derivative of a linear function is constant.
d) If y = f(x) , then the units of f'(x) are the units of x over the units of y.
e) The function f(x)
x + 3 is differentiable at x=-3.
f) If a function is differentiable at a point, then the function is also necessarily continuous at that point.
