Question

find the inverse in h(x)-4x+5​

Answer 1

Answer:

Inversion gives two forms for  

x

=

2

±

√

h

−

1

,

h

≥

1

Explanation:

The for this equation is a parabola

(

x

−

2

)

2

=

y

−

1

≥

0

,

and

so,  

y

≥

1

,

The parabola is symmetrical about its axis x = 2.

Explicitly, the inverse functions are

x

=

2

±

√

h

−

1

,

h

≥

1

, representing the halves of the parabola,

bifurcated by x = 2.l
