Answer:
Graph 3
Step-by-step explanation:
f(x) inverse = 1/f(x)
=> 1/(1/2x) + 1(1/4)
=> 2x + 4
=> Third graph (Second row, first one)

Answer: 38
So she has used two kinds of sugar, brown and powdered.
She used
cups of brown sugar and
cups of powdered sugar: we need to add the two numbers:
+
= 2+1+
=3
so the correct answer is 4.5
<h3>
You need to add 4 to both sides</h3>
The x term has a coefficient of 4. Take half of this to get 2, then square it to get 4. This is the value we add to both sides to get x^2+4x+4 = 5. Note how x^2+4x+4 factors into (x+2)^2

Another example: Let's say we started with x^2+6x = 1. To complete the square, we need to add 9 to both sides. I start with 6 (the x coefficient) and cut that in half to get 3, then I squared that to get 9. So we add 9 to both sides getting x^2+6x+9 = 10 which becomes (x+3)^2 = 10
Answer: The value of g(x) is x+3.
Step-by-step explanation:
Since we have given that
Here,
We need to find the value of g(x):
Hence, the value of g(x) is x+3.
