F(x) = 3x2 – 40x + 180 What is the rule for finding the vertex of the formula in Standard form? Use that rule to find the vertex of our formula, from above (Once you find the x value, plug it into the equation to find the value of f(x)). What do the x and f(x) values you got represent?

i really dont know

step-by-step explanation:

option: d is correct

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
