Want is the inverse of the function f(x)=2x-10

f

−

1

(

x

)

=

1

2

x

+

5

Explanation:

f

(

x

)

=

2

x

−

10

→

Replace the

f

(

x

)

with

y

y

=

2

x

−

10

→

Switch the places of the x and the y

x

=

2

y

−

10

→

Solve for y

x

+

10

=

2

y

y

=

1

2

x

+

5

The inverse is

f

−

1

(

x

)

=

1

2

x

+

5

The inverse is

f^-1(x)=1/2x+5

Step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
