Evaluating a Function In Exercises 29-34, evaluate the difference quotient and simplify the result. See Example 4. f ( x ) = 1 x − 2 f ( x + Δ x ) − f ( x ) Δ x
Evaluating a Function In Exercises 29-34, evaluate the difference quotient and simplify the result. See Example 4. f ( x ) = 1 x − 2 f ( x + Δ x ) − f ( x ) Δ x
Solution Summary: The author explains the formula used to calculate the value of the expression f(x+Delta x) and the function.
find the zeros of the function algebraically:
f(x) = 9x2 - 3x - 2
Rylee's car is stuck in the mud. Roman and Shanice come along in a truck to help pull her out. They attach
one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck
starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a
horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate
a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The
angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude
and its direction angle from the positive x-axis.
