Question

What is the inverse

x + 2?
© H(x) = 4x+2
h(c) = 1x-2
h(x) = 3x - 2
h(x) = 3x - 6

Answer 1

y= x+2

H(x)inverse = (x-2)/4

h(c)inverse=x+2

Explanation:

y=x-2

Find the inverse and first swich y and x around

x=y-2

Solve for y

x+2=y

H(x) is the same as saying y

y=4x+2

Swich the x and y around

x=4y+2

Solve for y

x-2=4y

(x-2)/4=y

So H(x)inverse = (x-2)/4

y=1x-2

x=1y-2

x+2=1y

So h(c)inverse=x+2

And so for for the rest of problems.
