Two statements below about functions and their inverses are true. Select two true statements.
A The graph of a function and its inverse are reflections across the y axis.
B The graph of a function and its inverse are reflections across the line y = 2.
To determine the inverse of a function algebraically, the first step is to switch x and y.
D To determine the inverse of a function algebraically, the first step is to find the reciprocal of the function.
E The graph of a function and its inverse are reflections across the x axis.
FIf a given relation is a function, then its inverse is necessarily a function as well.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
