If you look at the points, you can find out
Answer:
x = 81
Steps:
It says that y ~ √x
We have points (9, 18) as a guide.
We can write y = f(x) = a√x +b
Use points (9, 18) as a guide
18 = a√9 +b
18 = 3a + b
One solution might be a = 6, which means f(x) = 6√x
Thus when y = 54,
54 = 6√x
9 = √x
81 = x

Step-by-step explanation:
g(-7) = -7 + 2 = -5
Answer:
U cannot use factorisation method to solve this, we are to use formula method
