Answer:
D.) 8
Step-by-step explanation:
You can use the Pythagorean theorem because this is a right triangle:
a and b are the legs and c is the hypotenuse. The hypotenuse is always the longest side in a right triangle (since it is opposite the biggest angle). The two legs squared have to add up to the hypotenuse squared.
Fill in values:
Simplify exponents:
Isolate the variable. Subtract 225 from both sides:
Find the square root of both sides:
The missing leg length is 8.

<u><em>The third one is correct.</em></u> You cannot figure it out from the parent function, |x|, because they are all the same. As a result, you have to figure it out from the y-intercept. The y-intercept of a function most of the time is the <em>constant</em> of the function. The y-intercept here is <em>0.5</em>. Using this, you can find the corresponding graph. That would be the <u><em>third </em></u><u><em /></u><em /> option.
