Hey there!
When you write an equation in function notation, one side of the equation is, "f(x)".
You can replace x with another variable such as n if you are using a different one.
f(x) takes the place of y in an equation.
For example, the equation y = 3x + 2 in function notation is f(x) = 3x + 2.
Hope this helps!
The equation
a/4 = 2/3
do cross multiplication
8 = 3a
a = 8/3
Performing the expression.
= (a - 4) / 4
= (8/3 - 4) / 4
= (8-12 / 3)/4
= -4/3 / 4
= -1 / 3
So the answer is letter b.
Answer:
.31
Step-by-step explanation:
You do 3.99 divided by 13 to get the price of one

Answer:
D.
Step-by-step explanation:
Its a fifth degree function so it will have 5 roots.
One of the 3 roots is complex ( imaginary):- 4 + i so there must be another root value 4 - i because these roots always occur as conjugate pairs.
The fifth root must be real because you cant have just one imaginary root.
