Q. Find the inverse function in slope-intercept form (mx+b) :f(x)=−41x+15Answer: f−1(x)=
Write function as y: To find the inverse function, we first write the function as y=−(41)x+15.
Swap x and y: Next, we swap x and y to find the inverse. This gives us x=−41y+15.
Solve for y: Now, we solve for y to get the inverse function in slope-intercept form. We start by adding (1/4)y to both sides to isolate the terms with y on one side: (1/4)y+x=15.
Subtract x: Next, we subtract x from both sides to get 41y=15−x.
Multiply by 4: To solve for y, we multiply both sides by 4 to get y=4(15−x).
Simplify the equation: Simplify the equation to get y=60−4x. This is the inverse function in slope-intercept form.
