I Need Help Very Much The Last Tutor Left The Thing class=

Sagot :

f(x)= l -4x+3 l

that means

f(-2)= l -4(-2)+3 l = l8 +3l = l11l = 11

f(-1)= l -4(-1)+3 l = l 4+3l = l7l = 7

f(0)= l -4(0)+3 l = l3l = 3

f(1)= l -4(1)+3 l = l-4 +3l = l-1l = 1

f(2)= l -4(2)+3 l = l-8 +3l = l-5l = 5

The only thing that changes is that the image will always be the absolute value, it is a linear equation

_____________

the rate of change is the slope (m )

y = mx + b

m= -4

______________

_____________________________________

The average

m1 = (y2-y1)/ (x2-x1)

point

(x,y)

(x1,y1) =(1,1)

(x2, y2) =(2,5)

m1 = (5-1)/ (2-1) = 4/1

m1=4

m2= (y2-y1)/ (x2-x1)

(x,y)

(1,1)

(-2, 11)

m2= (11-1)/( -2-1)

m2= -10/3
