Please help I really don’t understand part a.

You can show that the function is one-to one by setting f(x)=f(y) and determining if f(x)=f(y)

Step-by-step explanation:

So, you could

(y-2)^3+8=(x-2)^3+8 and determine if x=y

(y-2)^3=(x-2)^3

=cube root both sides

y-2=x-2

y=x

func is 1 to 1

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
