Given f(x) = ax – b, what is f-1(x)?

(x) =

Step-by-step explanation:

let y = f(x) and rearrange making x the subject

y = ax - b ( add b to both sides )

y + b = ax ( divide both sides by a )

= x

Change y back into terms of x with x = (x) , then

(x) =

true

explanation:

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i
