Introduction

In mathematics, functions are used to describe the relationship between variables. The function $g$ is defined by $g(x) = (x + 14)(t - x)$ , where $t$ is a constant. This function is a quadratic function, and its graph in the $xy$ -plane is a parabola. In this article, we will explore the graph of $y = g(x)$ and find the value of $g(0)$ .

The Graph of y = g(x)

The graph of $y = g(x)$ is a parabola that opens downward. The vertex of the parabola is at the point $(t, 0)$ . The graph passes through the point $(24, 0)$ , which means that the value of $g(24)$ is equal to $0$ .

Finding the Value of t

Since the graph of $y = g(x)$ passes through the point $(24, 0)$ , we can substitute $x = 24$ and $y = 0$ into the equation $g(x) = (x + 14)(t - x)$ to find the value of $t$ .

0 = (24 + 14)(t - 24)

Simplifying the equation, we get:

0 = 38(t - 24)

Dividing both sides by $38$ , we get:

0 = t - 24

Adding $24$ to both sides, we get:

t = 24

Finding the Value of g(0)

Now that we have found the value of $t$ , we can substitute $x = 0$ into the equation $g(x) = (x + 14)(t - x)$ to find the value of $g(0)$ .

g(0) = (0 + 14)(24 - 0)

Simplifying the equation, we get:

g(0) = 14(24)

Multiplying $14$ and $24$ , we get:

g(0) = 336
