Answer:
9x^4+21x+6=0
Step-by-step explanation:
( 3x^2)^2+7(3x +2) -8=0
((3^2)*(x^2)^2)+(7*3x)+(7*2)-8=0
9(x^4)+21x+14-8=0
9x^4+21x+6=0
Answer:

Step-by-step explanation:
The multiplicative inverse of a number n is 
The product of the number and its multiplicative inverse = 1
n ×
= 1
Thus the multiplicative inverse of
is
= 
Answer:
The transformation in this figure is rotation.
Step-by-step explanation:
The transformation in this figure is rotation.
There are four types of transformation.
<u>Translation:</u>
Movement of the object without rotating it or changing its size.
<u>Reflection:</u>
Flipping the object about a line of reflection. The mirror image is formed after transformation.
<u>Dilation:</u>
Changing the size of a figure without changing its essential shape.
<u>Rotation:</u>
A rotation is a transformation that turns a figure about a fixed point called the center of rotation.An object and its rotation are the same shape and size, but the figures may be turned in different directions....

something worth noticing 
so, we're really graphing x+2, with a hole at x = 3, however, when x = 3, we know that f(x) = 5, but but but, when x = 3, x+2 = 5, so we end up with a continuous line all the way, x ∈ ℝ, because the "hole" from the first subfunction, gets closed off by the second subfunction in the piece-wise.
