The rate of change would be the coefficient of x. Let's see how this can be used to solve real-world word problems. Direct link to Teairra Pough's post What is the average rate , Posted 2 years ago. Determine the instantaneous velocity at \(t=2\) seconds Jan 13, 2023 OpenStax. Find the rate of change of a function from to . Suppose the position of a particle is given by \(x(t)=3 t^{3}+7 t\), and we are asked to find the instantaneous velocity, average velocity, instantaneous acceleration, and average acceleration, as indicated below. Observe that the accuracy of this estimate depends on the value of hh as well as the value of f(a).f(a). Try your calculations both with and without a monthly contribution say, $5 to $200, depending on what you can . So we could make a table here. To determine the rate of the change of the angle opposite to the base of the given right triangle, we must relate it to the rate of change of the base of the triangle when the triangle is a certain area. Find the slope of the tangent to the graph of a function. These two values,and, only happen at a single instant in time.
