Question

What value of x will give the minimum value for x^2- 14x + 3?


Please help me!!

Answer 1

Hello Feep! Since you are trying to to find the minimum value, you can use the vertex formula.
a = 1
b = -14
Vertex Formula.

`x = -(b)/(2a)`

`x = -((-14))/(2(1))`
Distrubute the negative to the -14 making it 14

`x = ((14))/(2(1))`
Times the denominator 2 * 1 = 2

`x = ((14))/(2)`

`x = 7`
So 7 will give the minimum value for x^2- 14x + 3
