Answer:
<h2>B) x² - 4</h2>
Step-by-step explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x + n) - shift the graph n units to the left
f(x - n) - shift the graph n units to the right
------------------------------------------------------------------------------
The vertex of the function f(x) = x² is in the origin.
We have the vertex (0, -4). Therefore, the graph has been moved by 4 units down.
f(x) - 4 = x² - 4
X+2y=6
x-y=3x=6-2y
x=3+y
6-2y=3+y
3=3y
y=1
x=3+1
x=4
Answer: (4;1)
Answer: 9
Step-by-step explanation:
Given:
n², n = 3
Plug-in:
(3)²
Square 3:
3 * 3 = 9, so (3)² = 9
Simplify:
9
Answer:
it's answer is B
Step-by-step explanation:
f (x)=x (x-2)+3 (x-2)
=x2+x-6
Answer:
(5√x) / [(3√x)-4]
Step-by-step explanation:
You cannot solve this because 5, 3, and 4 are not factors/multiples of one another
I simplified it though
when the exponent is 1/2, it is the same as taking the square root of something
5x^1/2 is the same as 5√x
3x^1/2 is the same as 3√x
