Answer:
f(x) = x/4
Step-by-step explanation:
To find the inverse of a function replace the positions of x and y. Then isolate y.
y = 4x
x = 4y
x/4 = y
f(x) = x/4
Answer:
<u> y = 19/36</u>
Step-by-step explanation:
Assuming that what you want is the value of y, you can pass all the right side stuff to the left, and the y to the right:
2/3 + 15/6 = 6y
Then you can sum the fractions on the left by using the same denominators:
4/6 + 15/6 = 6y ==> 19/6 = 6 * y
then you can pass the 6 that is multiplying on the right to the left - now dividing:
<u> y = 19/36</u>
The sum of a number and 2
x + 2
is twice the number
2x

Answer: 
Step-by-step explanation:
Find the x-coordinate of the vertex with this formula:
In this case:
Substituting values, we get:
Now we can substitute the coordinates of the vertex into the equation 
and then solve for "c".
Then:
