Verify Mean Value Theorem: f(x)=3x^2+6x+7 on [-2,3]

In summary, the Mean Value Theorem is a fundamental theorem in calculus that states that for a function that is continuous on a closed interval and differentiable on the open interval, there exists a point within the interval where the slope of the tangent line is equal to the slope of the secant line connecting the endpoints. To verify this theorem, the function must first be continuous on the closed interval and differentiable on the open interval. The Mean Value Theorem is verified using the formula f'(c) = (f(b) - f(a))/(b - a), where c is the point within the interval that satisfies the theorem. This theorem can only be applied to functions that meet the necessary criteria. In real-world applications, it is used in

Verify that the function satisfies the hypotheses of the Mean Value Theorem on the given interval. Then find all numbers that satisfy the conclusion of the Mean Value Theorem.


f(x)=3x^2+6x+7 on [-2,3]

so f(3)-f(-2)=f'(x)(3+2)

i get 52-7=(6x+6)(5)

then 45=30x+30

then 5=30x

and x=1/6

where am i going wrong?

Related to Verify Mean Value Theorem: f(x)=3x^2+6x+7 on [-2,3]

1. What is the Mean Value Theorem?

The Mean Value Theorem is a fundamental theorem in calculus that states that for a function that is continuous on a closed interval and differentiable on the open interval, there exists a point within the interval where the slope of the tangent line is equal to the slope of the secant line connecting the endpoints.

2. How do you verify the Mean Value Theorem for a given function?

To verify the Mean Value Theorem for a given function, you need to first ensure that the function is continuous on the closed interval and differentiable on the open interval. Then, you can use the formula f'(c) = (f(b) - f(a))/(b - a), where c is the point within the interval that satisfies the theorem.

3. What is the function used to verify the Mean Value Theorem?

The function used to verify the Mean Value Theorem is f'(x), the derivative of the given function.

4. Can the Mean Value Theorem be applied to all functions?

No, the Mean Value Theorem can only be applied to functions that are continuous on a closed interval and differentiable on the open interval.

5. How is the Mean Value Theorem used in real-world applications?

The Mean Value Theorem is used in real-world applications, such as in physics and engineering, to determine average rates of change and to approximate values of functions at specific points. It is also used in economics to calculate marginal rates of production and in statistics to analyze data.
