4 0

Answer: 1.  1*f*(x)-(-(x+4)^2-4)=0

STEP

1

:

Equation at the end of step 1

 fx - x2 - 8x - 12  = 0

STEP

2

:

Solving a Single Variable Equation:

2.1     Solve   fx-x2-8x-12  = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*f*(x)-((x-1)^2)=0

STEP

1

:

1.1     Evaluate :  (x-1)2   =    x2-2x+1

Equation at the end of step

1

:

 2fx - x2 + 2x - 1  = 0

STEP

2

:

Solving a Single Variable Equation:

2.1     Solve   2fx-x2+2x-1  = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Which is the graph of the function f(x) = -√x?
Virty [35]

Answer:

Step-by-step explanation:

The last (fourth) graph is that of the parent function y = √x.  The negative sign in front of √x leads to reflection of this parent function graph in the x-axis.  Thus, the correct graph of f(x) = -√x is the first one.

liq [111]

Answer:

Rita = 300

John = 900

Rodell = 925

Step-by-step explanation:

rita = x (let

john = 3x ( john swims three times more than rita

rodell = 25 + 3x ( rodell swims 25 more than john

x + 3x + 25 + 3x = 2125

or, 7x + 25 = 2125

or, 7x = 2125 - 25

or, x = 2100/7

x = 300

hence,

x = 300

3x = 3 × 300

= 900

25 + 3x = 25 + 900

= 925
