x = √11
Step-by-step explanation:
2x² - 1 = 21
add 1 to both sides
2x² - 1 + 1 = 21 + 1
simplify
2x² = 22
x² = 22 / 2
x = √11
2, because 132 divided by 3 equals44 and 132 plus 44 equals 176

Answer:
A. horizontal reflection
Step-by-step explanation:
Given:


To identify the type of transformation.
Solution:
On close observation of the functions we find the that sign of
has changed in
with other terms being constant.
<em>Thus, the transformation statement can be given as:</em>

As:


The transformation
describes horizontal reflection of function across the y-axis.
Thus,
is horizontally reflected across y-axis to get
.
