Q. What is the inverse of the functiong(x)=−2(x−4)?g−1(x)=
Replace g(x) with y: To find the inverse of the function g(x)=−2(x−4), we first replace g(x) with y to make the equation easier to manipulate. So we have y=−2(x−4).
Swap x and y: Next, we swap x and y to find the inverse. This gives us x=−2(y−4).
Solve for y: Now, we solve for y. Start by dividing both sides by −2 to isolate the term with y. This gives us −2x=y−4.
Add 4 to both sides: Next, add 4 to both sides to solve for y. This gives us y=−2x+4.
Inverse function expression: The expression we have now represents the inverse function. So, g−1(x)=−2x+4.
