The problem gives a quadratic equation in factored form: $y = 2.1(x-1)(x-9)$. We need to find the x-intercepts of the graph of this equation and enter them as ordered pairs (points).

1. Problem Description

The problem gives a quadratic equation in factored form: $y = 2.1(x-1)(x-9)$. We need to find the x-intercepts of the graph of this equation and enter them as ordered pairs (points).

2. Solution Steps

To find the x-intercepts, we need to find the values of $x$ when $y = 0$. The equation is given as $y = 2.1(x-1)(x-9)$. Setting $y=0$, we get:

$0 = 2.1(x-1)(x-9)$

Since $2.1$ is a constant and not zero, we have:

$(x-1)(x-9) = 0$

This equation is satisfied if either $(x-1) = 0$ or $(x-9) = 0$.

If $(x-1) = 0$, then $x = 1$. The x-intercept is $(1,0)$.

If $(x-9) = 0$, then $x = 9$. The x-intercept is $(9,0)$.

The leftmost x-intercept is the one with the smaller x-value, which is $(1, 0)$. The rightmost x-intercept is $(9, 0)$.

3. Final Answer

The leftmost x-intercept is $(1, 0)$.

The rightmost x-intercept is $(9, 0)$.
