Answer:
The inverse function is f(x) = x^2 - 3
Step-by-step explanation:
To find the inverse of any function, start by switching the x and f(x) values.
f(x) = √(x + 3)
x = √(f(x) + 3)
Now solve for the new f(x). The result will be your inverse function.
x = √(f(x) + 3)
x^2 = f(x) + 3
x^2 - 3 = f(x)

step 1
Find out the ounces of orange juice concentrate used yesterday
Let
x ----> ounces of orange juice concentrate used yesterday
y ---> ounces of water used yesterday
we know
that
----> equation A
----> equation B
substitute equation B in equation A
solve for x
step 2
today she wants to make twice as much orange juice.
To find out how much orange juice concentrate she needs, multiply the ounces of orange juice concentrate used yesterday by 2
so
Answer:
<em>(C). </em>
<em> = ( x + 4 )² ; x ≥ 0</em>
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
add 3 to each side to isolate the 3x alone on one side
3x=6/ divide by 3 to isolate and simplify
x=2
