Find f(2) given f(x)=−3x3+x2−3

-23

Step-by-step explanation:

f(2) = -3 (2) ^ 3 + (2) ^2 -3

= -3 * 8 + 4 -3

= - 24 + 4 - 3

= -23

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)
