Q. Assuming that x is in the appropriate domain, find a formula forh−1(x)=1−(sin−1(2(−8−x)))
Start with given equation: To find the formula for the inverse function h−1(x), we need to express x in terms of h. We start with the given equation for h−1(x):h−1(x)=1−sin−1(2−8−x)Let's denote h−1(x) as y for simplicity:y=1−sin−1(2−8−x)
Isolate sin−1 term: Now we need to solve for x. First, we isolate the sin−1 term by moving everything else to the other side of the equation:sin−1(2−8−x)=1−y
Apply sine function: Next, we apply the sine function to both sides to remove the inverse sine, keeping in mind that sin(sin−1(u))=u for all u in the domain of sin−1:sin(sin−1(2−8−x))=sin(1−y)2−8−x=sin(1−y)
Multiply by 2: Now we multiply both sides by 2 to get rid of the denominator:−8−x=2sin(1−y)
Isolate x: Next, we isolate x by moving the −8 to the other side:−x=2sin(1−y)+8
Multiply by −1: Finally, we multiply both sides by −1 to solve for x:x=−2sin(1−y)−8
Replace y with h−1(x): Now we replace y with h−1(x) to get the formula for the inverse function in terms of x: x=−2sin(1−h−1(x))−8 However, this is not quite correct because we need to express h−1(x) in terms of x, not the other way around. We need to go back and correct this mistake.
