Answer:
Step-by-step explanation:
f(x)=x^2 represents a parabola with vertex at (0, 0), that opens up.
If we translate this graph h units to the right, then g(x) will be:
g(x) = (x - h)^2.
If we translate the graph of f(x)=x^2 k units up, then g(x) will be:
f(x)=x^2 + k
Next time, please indicate whether you are shifting the original graph to the right or to the left, and/or up or down.
So you can multiply 65 by 15% or .15 and get 9.75
Subtract that from 65 and get $55.25 as the sales price
Just replace x^2+4 with a
factor out on left side
(x^2+4)^2+32=12(x^2+4)
replace x^2+4 with a
a^2+32=12a
minus 12a both sides
a^2-12a+32=0
solve
factor
what 2 numbers mulitply to get 32 and add to get -12
-4 and -8
(a-4)(a-8)=0
set each to zero
a-4=0
a=4
a-8=0
a=8
remember
a=x^2+4
so
4=x^2+4
0=x^2
0=x
8=x^2+4
4=x^2
+/-2=x
x=-2, 0, 2
