The y-value of the vertex is positive 3, as shown by the +3 on the right hand side of the equation, and the x-value is -1, from the (x+1)^2 (remember, when the number is inside the brackets, flip the sign) The vertex would be (-1, 3)
If you are looking for a rigorous answer (calculus), we must find the mininum point of the equation: f(x) = (x+1)^2 + 3 f
f'(x) = 2(x+1) = 2x + 2
2x + 2 = 0
x = -1
f(1) = (-1 + 1)^2 + 3
f(1) = 0 + 3 = 3
(-1, 3)
Oooh! I love this kind of math, so easy to do!
Like I say ALL the time, if you know how to solve percentages you know how to solve anything that deals with percentages. If you don't izz all gucci! :D
To solve a percentage make it a decimal & multiply. :) (SIMPLE)
- .300 % multiplied by 1000 = 300 :D you would pay 300$ a year obviously!
I'm not that great at percentage math, although it is fairly easy. I hope you can use this information too push you closer too the answer! Good Luck! <3
