Let $f$ be a function with $f(1) = 4$ such that for all points $(x, y)$ on the graph of $f$ , the slope is given by $\frac{3x^2 + 1}{2y}$

Introduction

In mathematics, a function is a relation between a set of inputs, called the domain, and a set of possible outputs, called the range. The graph of a function is a visual representation of the function, where each point on the graph corresponds to a value of the function. The slope of a graph at a given point is a measure of how steep the graph is at that point. In this article, we will explore the concept of a function with a given slope and use it to find the slope of the graph of a specific function.

The Given Function

Let $f$ be a function with $f(1) = 4$ . This means that when the input of the function is 1, the output is 4. The slope of the graph of $f$ at any point $(x, y)$ is given by the formula $\frac{3x^2 + 1}{2y}$ . This formula tells us that the slope of the graph at any point is equal to the ratio of the quadratic expression $3x^2 + 1$ to the linear expression $2y$ .

Finding the Slope of the Graph

To find the slope of the graph of $f$ , we need to find the derivative of the function. The derivative of a function is a measure of how the function changes as the input changes. In this case, we are given the slope of the graph at any point, so we can use this information to find the derivative of the function.

Let's start by finding the derivative of the quadratic expression $3x^2 + 1$ . Using the power rule of differentiation, we get:

\frac{d}{dx}(3x^2 + 1) = 6x

Now, let's find the derivative of the linear expression $2y$ . Using the power rule of differentiation, we get:

\frac{d}{dy}(2y) = 2

Now, we can use the formula for the slope of the graph to find the derivative of the function:

\frac{d}{dx}f(x) = \frac{6x}{2y}

This is the derivative of the function, which represents the slope of the graph at any point.

Finding the Value of $y$

We are given that $f(1) = 4$ , which means that when the input of the function is 1, the output is 4. We can use this information to find the value of $y$ .

Let's substitute $x = 1$ and $f(x) = 4$ into the formula for the slope of the graph:

\frac{3(1)^2 + 1}{2y} = \frac{d}{dx}f(1)

Simplifying the expression, we get:

\frac{4}{2y} = \frac{d}{dx}f(1)

Now, we can use the fact that $f(1) = 4$ to find the value of $y$ :

\frac{4}{2y} = \frac{d}{dx}f(1) = \frac{6(1)}{2(4)} = \frac{3}{4}

Solving for $y$ , we get:

y = \frac{4}{2} \cdot \frac{4}{3} = \frac{8}{3}

Conclusion

In this article, we explored the concept of a function with a given slope and used it to find the slope of the graph of a specific function. We found that the derivative of the function is given by the formula $\frac{6x}{2y}$ , and we used this information to find the value of $y$ . The value of $y$ is $\frac{8}{3}$ , which represents the output of the function when the input is 1.
