Let g(x) = x^2 + bx + c. if g(2) = 0
and g(-3) = 0, find b + c.

Step-by-step explanation:

The given function is

If g(2)=0, then we can substitute x=2 and g(x)=0 to get:

...(1)

Also g(-3)=0

...(2)

Equation (1) - equation (2) gives

b=1

Put b=1 into equation 1

Therefore

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
