1. XYZ Inc uses the following function to model the raise an employee will receive each year: f(x)=35000+650x. 123 Corp uses a different model for raises: g(x)=30000+200(1.45)x‒1. If x represents the number of years an employee has worked, 1) Discuss the parameters for each function and what they mean in the context of the problem you have been given. 2) Determine when XYZ Inc. has a better plan for raises and then when 123 Corp. has a better plan and how you know. 2. The standard form for a quadratic function is given by the function f(x)=2x2‒8x‒24. 1) Rewrite the function two equivalent forms: factored form and vertex form. 2) Use any form to sketch a graph of the function and label the key characteristics. 3) Use different forms of the quadratic function to determine the zeros, axis of symmetry, vertex, and max/min of the quadratic function.

answer: this is not a question

step-by-step explanation: this is a answer

a.   we have two

lines:   y = 4-x   and  

y = 8-x^-1

given two simultaneous equations that are both to be

true, then the solution is the points where the lines cross. the intersection is

where the two equations are equal. therefore the solution that works for both

equations is when

4-x = 8-x^-1

this is where the two lines will cross and that is the

common point that satisfies both equations.

b.   4-x = 8-x^-1

  x           4-x       8-x^-1

-3           7        

8.33

-2           6         8.5

-1           5         9

  0           4        

-

  1           3        

7

  2           2        

7.5

  3           1         7.67

the table shows that none of the x values from -3 to 3 is

the solution because in no case does

4-x = 8-x^-1

to find the solution we need to rearrange the equation to

find for x:

4-x = 8-x^-1

multiply both sides with x:

4x-x^2 = 8x-1

x^2+4x-1=0

x= -4.236, 0.236

therefore there are two points that satisfies the

equation.

find y:  

x=-4.236

y = 4-x   = 4 – (-4.236)

= 8.236

y = 8-x^-1 =   .236)^-1

= 8.236

x=0.236

  y = 4-x   = 4 – (0.236) = 3.764

y = 8-x^-1 =   8-(0.236)^-1

= 3.764

thus the two lines cross at 2 points:

(-4.236, 8.236) & (0.236, 3.764)

c.   to solve

graphically the equation 4-x = 8-x^-1

we would graph both lines: y = 4-x   and   y

= 8-x^-1

the point on the graph where the lines cross is the

solution to the system of equations.

just graph the points on part b on a cartesian coordinate

system and extend the two lines.   the

solution is, as stated, the point where the two lines cross on the graph.
