Answer:

y = -\frac{1}{3}x + 3

Step-by-step explanation:

2 = −⅓[3] + b

−1

3 = b \\ \\ y = -\frac{1}{3}x + 3

Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>RATE OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so 3 becomes −⅓.

What is the inverse of x^2-4x+5
lisabon 2012 [21]

we are given

f(x)=x^2-4x+5

Since, we have to find inverse of this function

step-1: we set f(x)=y

y=x^2-4x+5

step-2: switch x and y

x=y^2-4y+5

step-3: Solve for y

y^2-4y+(5-x)=0

now, we can use quadratic formula

y=\frac{4+\sqrt{4^2-4(5-x)} }{2}

f^{-1}(x)=\sqrt{x-1}+2

or

f^{-1}(x)=-\sqrt{x-1}+2..............Answer
