Question

In addition to knowing the rate of change of a function, it is useful to know the starting value. What is the starting value of a function?

Check all that applies.

A The starting value of a function is at (0,0).

B The starting value is the output of the function when the input has a value of 0.

C The starting value is (0, b) where b is the y-value when x is at 0.

D The starting value of a function is when y = 0

Answer 1

The correct options regarding the starting value of a function are:

B. The starting value is the output of the function when the input has a value of 0.

C. The starting value is (0, b) where b is the y-value when x is at 0.

Option A is incorrect because not all functions have a starting point at (0,0); it depends on the specific function.

Option D is incorrect because the starting value of a function does not necessarily refer to when y = 0; it specifically refers to the value of the function (y) at a given input (usually x = 0).
