Directions

Read the following questions. Choose the right answer.

There is only ONE correct answer to each question.

Let f(x) = x² − 3x + 4. The slope of the tangent to the curve defined by f(x) at the point (0,4) is:

  1. -3
  2. -1/3
  3. 1
  4. 4
Show answer

Correct answer: A. -3

Why

f'(x) = 2x−3; at x=0, the slope is f'(0) = −3.
