First, let's find g(4). After we find it, we can substitute the value into .
To find g(4), we need to substitute x = 4 into the function , as shown below:
Now that we have found g(4) = 9, we can substitute this value in for in
.
f(g(4)) is equal to 28.
Answer:
k = 5,
y = 5x
Step-by-step explanation:
If y is proportional to x,
y ∝ x
Then the equation will be
y = kx
Her k = proportionality constant.
Now we choose a point from the given table.
Let the point is (2, 10).
By putting the values of x and y in the equation,
10 = 2×k
k =
k = 5
This will be true for any point we choose from the table.
And the equation will be y = 5x
