Answer:B

Step-by-step explanation:

if you substitute any convenient value of x into f(x)= 2x-1 you see that it holds true when looking for the corresponding value of y.

For example,if you substitute x=5 into function B you get:

f(5)= 2(5) -1 = 10- 1 =9

Now,if you go on x =5 on the graph and check the corresponding value of y you that this value it is indeed 9.

Answer:

<h2>B) f(x) = 2x - 1</h2>

Step-by-step explanation:

<em>Look at the picture.</em>

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept → (0, b)</em>

The formula of a slope:

m=\dfrac{\Delta y}{\Delta x}=\dfrac{rise}{run}

We have:

rise=4\\run=2\\b=-1

The slope:

m=\dfrac{4}{2}=2

Substitute to the equation of a line:

y=2x+(-1)=2x-1

   y - y₁ = m(x - x₁)
y - (-1) = 4[x - (-3)]
   y + 1 = 4(x + 3)
   y + 1 = 4(x) + 4(3)
   y + 1 = 4x + 12
       - 1           - 1
         y = 4x + 11

The answer is B.

For the function f(x) = x + 9, find (f o f-1)(5) A. 14 B. 5 C. -5 D. 25
Alex Ar [27]
F-1:
y=x+9
y-9=x
x-9=f-1
f-1(14)=14-9=5 f-1(5)=5-9=-4  f-1(-5)=-5-9=-14 f-1(25)=25-9=16
f(14)=14+9=24 f(5)=5+9=14 f(-5)=9-5=4 f(25)=25+9=34

Find the inverse of the function f(x)=5x-6/x+2
Naily [24]

Answer:

  f^{-1}(x)=\dfrac{2x+6}{5-x}

Step-by-step explanation:

Swap x and y, then solve for y.

x=\dfrac{5y-6}{y+2}\\\\x(y+2)=5y-6\\\\xy+2x=5y-6\\\\2x+6=5y-xy\\\\y=\dfrac{2x+6}{5-x}\\\\f^{-1}(x)=\dfrac{2x+6}{5-x}
