Answer:

$Domain\ =\ \{x: 9,10,11....16\}$

<em></em> $Range\ =\ \{y:290, 315,340.....465\}$ <em></em>

Step-by-step explanation:

Given

$y = 25x + 65$

Required

Determine the range and domain when x = 9 to 16

The domain is the set of

$Domain\ =\ \{x: 9,10,11....16\}$

Solving for the range;

<em>When x = 9</em>

<em></em> $y = 25 * 9 + 65$ <em></em>

<em></em> $y = 225 + 65$ <em></em>

<em></em> $y = 290$ <em></em>

<em></em>

<em>When x = 10</em>

<em></em> $y = 25 * 10 + 65$ <em></em>

<em></em> $y = 250 + 65$ <em></em>

<em></em> $y = 315$ <em></em>

<em></em>

<em>When x = 11</em>

<em></em> $y = 25 * 11 + 65$ <em></em>

<em></em> $y = 275 + 65$ <em></em>

<em></em> $y = 340$ <em></em>

<em></em>

<em>You continue till you get to x = 16</em>

<em>---</em>

<em>--</em>

<em>-</em>

<em>When x = 16</em>

<em></em> $y = 25 * 16 + 65$ <em></em>

<em></em> $y = 400 + 65$ <em></em>

<em></em> $y = 465$ <em></em>

<em></em>

<em>Hence; the range is</em>

<em></em> $Range\ =\ \{y:290, 315,340.....465\}$ <em></em>
