Answer:
Step-by-step explanation:
Foil the equation!
1. You see that is to the second power so it means this
2. Then you use the Foil method. First, Outside, Inside, and Last.
3. Combined like terms
4. Answer!
A tip you can use to avoid Foil is this mental math trick: (Keep in mind this only works if the polynomial is being squared.)
1. Multiply the first number by itself =
2. Add the first number by itself =
3. Multiply the last number by itself =
4. Combined to form your answer =
NOTE: This is the same thing as a foil but it uses mental math so it takes less time!
Alternatively, you can write radicals as rational exponents, so that you get
Then recalling that
, you have
Answer:
The answer is x ≥ -3/4

Answer:
A) Reflect the graph of the first function across the x-axis, translate it pi/4 units to the left, and translate it 2 units up
Step-by-step explanation:
We are given
parent function as
and new function as
We can also write as new function as
We can see that
x-value is added by pi/4
So, it is shifted left side pi/4
and y-value is added by 2 units
so, it moves 2 units upward
we can see that
y-value is multiplied by -1
so, it reflected about x-axis
so,
A) Reflect the graph of the first function across the x-axis, translate it pi/4 units to the left, and translate it 2 units up
