2 Select the correct answer.

The domain, range, and x-intercept of a one-to-one function are shown.

domain: 1 > 2
range: y = -3
x-intercept: (11,0)

Which set of information could be characteristics of the function's inverse?

a) domain: 1 > -2 range: y > 3; x-intercept (-11,0)

b) domain: 1 > 2 range: y = -3; xintercept: (-11,0)

c) domain: 1 > -3; range: y > 2; y-intercept: (0,11)

d) domain: 1 > 3 range: y > -2; y-intercept: (0,11)

i dont know what you want me to answer for this but im guessing 2: 11?

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81

just a girl thing, i think im cute when im not lol
