Y-intercept means x=0 but judging from the question you only gave f(x) which means Y
And so I think the only valid answer there is
Y= 0.25
X=0
Hello, It is very simples.
Look it :
Let a^3 - b^3 = ?
Add on both th side -3a^2b + 3ab^2
a^3 -3a^2b + 3ab^2 -b^3 = ?
-3a^2b+3ab^2
The firs equation is = (a - b)^3
Then,
(a - b)^3 = ? + 3a^2b - 3ab^2
Passing -3a^2b + 3ab^2 to the left side:
But changing the sinal
? = (a - b)^3 + 3a^2b - 3ab^2
? = (a - b)^3 + 3ab ( a - b)
Putting (a - b) as commun factor
? = (a - b).[ 3ab + (a - b)^2 ]
As (a - b)^2 = a^2 - 2ab + b^2
Then,
? = (a - b).[ 3ab + a^2 -2ab +b^2]
? = (a - b).( a^2 + ab + b^2)
I hope helps!

The number of stamps and the cost are illustrations of unit rates
40 stamps would cost $22
The cost of 15 postage stamps is $8.25
Start by calculating the unit rate of the stamps.


So, the number of stamps for $22 is calculated by dividing $22 by the unit rate.
So, we have:


Hence, 40 stamps would cost $22
