For each, you'll use the slope formula 
m = (y2-y1)/(x2-x1)

For function f, you'll use the two points (1,6) and (2,12) since x ranges from x = 1 to x = 2 for function f

The slope through these two points is 
m = (y2-y1)/(x2-x1)
m = (12-6)/(2-1)
m = 6/1
m = 6

-------------------------------------------

For function g, you'll use (2,4) and (3,20)

The slope through these two points is
m = (y2-y1)/(x2-x1)
m = (20-4)/(3-2)
m = 16/1
m = 16

-------------------------------------------

For function h, you'll use (0,-6) and (2,-18). The y coordinates can be found by plugging in x = 0 and x = 2 respectively into h(x)

The slope through these two points is
m = (y2-y1)/(x2-x1)
m = (-18-(-6))/(2-0)
m = (-18+6)/(2-0)
m = (-12)/(2)
m = -6

-------------------------------------------

The order from left to right is: h, f, g

Which of the following is a factor of 7x2 - 12x - 4? (6 points)
grin007 [14]

Answer:

We conclude that 'None of the above' is the correct answer.                    

Step-by-step explanation:

Given the expression

7x^2\:-\:12x\:-\:4

Breaking the expression into groups

7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)

Factor out x from 7x^2\:+\:2x

=x\left(7x+2\right)

Factor out -2 from \left(-14x-4\right)

=-2\left(7x+2\right)

so the expression becomes

7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)

                         =x\left(7x+2\right)-2\left(7x+2\right)

Factor out the common term 7x+2

                         =\left(7x+2\right)\left(x-2\right)

Therefore, from the given options, we conclude that 'None of the above' is the correct answer.
