-- It'll be a lot easier if you clean up the function first.
You're not changing the function. You're just making it
easier to read and work on without mistakes.
Notice that 3x3=9 , so the function is f(x) = 9 - 4x + 5
Combine like terms, and the function is f(x) = 14 - 4x .
Much easier to work with.
-- Now, when somebody tells you to evaluate the function <em>for some number</em>,
just take their number, write it in place of 'x',and see what you've got.
Example:
f(x) = 14 - 4x
Evaluate f(x) for x = 3.
-- Write 3 in place of 'x' in the function: f(3) = 14 - 4(3)
-- 4(3) = 12 . So the function is f(3) = 14 - 12
-- Finish up the subtraction : <em> f(3) = 2</em>
You just evaluated f(x) for x=3.
Nice job !

Answer:
Is there a type of equation your looking for or do you want the straight up answer?
Step-by-step explanation:
Answer:
y = 112
Step-by-step explanation:
If y varies directly as the square of x
mathematically;
y ∝ x²
y = kx² where 'k' is the constant of proportionality
let u know the value of k for this equation by making k the subject of the formular from y = kx²
divide both sides by x²
k = y / x²
given that y = 567 x = 9
k = 567/(9)²
k = 567/81
k = 7
now to get the value of y when x = 4
from the equation conneting x, y,
y = kx²
y = 7 × (4)²
y = 7 × 16
y = 112
Given:
iq1 - 52
iq3 - 72
iq3 - iq1 = iqr
72 - 52 = 20
inner fence = minor outlier
20 * 1.5 = 30
72 + 30 = 102
52 - 30 = 22
outer fence - major outliers
20 x 3 = 60
72 + 60 = 132
50 - 60 = -10
