If f(x) and its inverse function, f Superscript negative 1 Baseline (x), are both plotted on the same coordinate plane, where is
bearhunter [10]

Answer:

(2,2)

Step-by-step explanation:

step 1

Find the equation of f(x)

is a line that passes through the points (0,6) and (3,0)

Find the slope

m=(0-6)/(3-0)=-2

The function f(x) in slope intercept form is equal to

f(x)=-2x+6

step 2

Find the inverse

Let y=f(x)

y=-2x+6

Exchange the variables x for y and y for x

x=-2y+6

Isolate the variable y

2y=-x+6

y=-0.5x+3

Let

f^{-1}(x)=y

f^{-1}(x)=-0.5x+3

step 3

Solve the system of equations

f(x)=-2x+6

f^{-1}(x)=-0.5x+3

equate both functions

-0.5x+3=-2x+6

solve for x

2x-0.5x=6-3

1.5x=3

x=2

substitute the value of x in any of the functions

f(x)=-2(2)+6=2

The solution is the point (2,2)

therefore

Their point of intersection is (2,2)

Show work for repeated subtraction to divide 35÷4
Sonja [21]
35/4

You'd start by dividing 4 into 3. Since three is smaller it will not work. So you then divide it into 35. 35/4=8.75

Put these in order of smallest first 0.5,55%,3/5
taurus [48]
0.5 can also be written 0.50

55% is converted to 0.55

3/5 is 0.6 or 0.60

So 0.50, 0.55, 0.60

Or .5, 55%, 3/5
