Is (5, 10), (-8, 3), (-1, 7), (-5, 10) A Function ?

ankoles [38]

Answer:

Step-by-step explanation:

Notice that the inputs {5, -8, -1, -5} are all different. So we can immediately conclude that this is a function.

If the inputs were {5, -8, -1, 5}, this would not be a function, as the same input value (5) would result in two different outputs.

Which explains how to show that

alexgriva [62]

Answer:

c. Substitute

Step-by-step explanation:

A graph of the function on the left shows the parabola touches the x-axis at x = -8/3. That is, the vertex is on the x-axis. It crosses the y-axis at y = 64.

<h3>Show a value is a root</h3>

A given solution to an equation can be verified by substituting that value into the equation an showing the result is a <em>true statement</em>. Here, the value x=-8/3 is a root of the given equation because that value makes the equation true.

$9\left(-\dfrac{8}{3}\right)^2+48\left(-\dfrac{8}{3}\right)+64=0\\\\9\left(\dfrac{64}{9}\right)-\left(\dfrac{48\cdot8}{3}\right)+64=0\\\\64-\dfrac{3\cdot2\cdot8\cdot8}{3}+64=0\\\\64-2\cdot64+64=0\\\\0=0\qquad\text{True}$
