You were my last hope and guess what you save me

[@keyarana1425]

Thank you , it helped a lot.

[@94D33M]

-b/2a came from the fact that this is a quadratic equation which means if you differentiate it you'll get 4x+5, and minimum or maximum occurs where dy/dx = 0, so 4x + 5 = 0, so x = -1.25 . Plug in this in the equation to get 0.875. We know that equation is opening upward (positive coefficient of x^2) and therefore 0.875 is the minimum.

Wow.
Thanks Alot

thanks a bunch
I've got an upcoming SAT test and I'm doing really good but then stumbled on a question in which I must calculate the minimum value of the function.
I read its explanation but was left puzzled as it used a rule of: a(x-h)+k where h is the minimum
I have not yet taken this specific rule at school so yours is a life saver

Hey there!
There is also this formula they taught us at 10th grade. to find the maximum or minimum value without finding the x in :
ax² + bx + c
you can simply devide Δ by 4a to find the value of Y.

x² - 2x + 3 in this eq by applying this method the ans is coming 3 but its min. Value is 2

[@babihutan5949]

so is this method wrong?

[@amaneshomemadedonuts8222]

MY BRAIN ISINT BRAINING

[@phoenixuprise6709]

Can someone please explain how he got f(-1.25)=0.875 at the end?
I don't know how he solved f(-125)=2(-125)2+5(-125)+4 to get 0.875
I'm super confused.

[@brazucahciczarmy1120]

Just plug it in the calculator.

[@yasir-k4988]
