Let's figure out the other angle in each triangle.
A triangles' angles add up to 180°, so
XYZ has angles measuring 29, 54, and 97°.
X'Y'Z' has angles measuring 29, 59, and 92°.

All dilations are similar, meaning that if you shrink one down to the size of the other, they will be the same. Consider two triangles that have been dilated. The sides have changed but the angles are the same.

Triangle XYZ and triangle X'Y'Z' have angle measures that are not the same, therefore they are not similar. All dilations are similar, so X'Y'Z' cannot be a dilation of XYZ.

1. Evaluate the function f(x)=3x-1 using the domain of -2, 0, 3, and 5. Results are to be shown in a table.

Answer:

See explanation

Step-by-step explanation:

You are given the function $f(x)=3x-1$

The domain of the function are all possible values of variable x, so you can find f(x) for x=-2, 0, 3, 5:

$f(-2)=3\cdot (-2)-1=-6-1=-7\\ \\f(0)=3\cdot 0-1=0-1=-1\\ \\f(3)=3\cdot 3-1=9-1=8\\ \\f(5)=3\cdot 5-1=15-1=14$

The table is

$\begin{array}{cc}x&f(x)\\-2&-7\\0&-1\\3&8\\5&14\end{array}$

The inverse function $f^{-1}(x)$ has the domain which is the range of the function f(x) (all possible values of f(x)), so the domain of inverse function is {-7,-1,8,14}
