Answer:
From the above image when the input of f(x) is 9 the output is 1
So f^-1(1) is just the reverse when the input is 1 the output is 9
So f^-1(1) = 9
Hope this helps
Answer:
X = 10 and X = -4
Step-by-step explanation:
(x-3)^2-38=11
(x-3)^2 = 11 +38
(x-3) ^2 = 49
Taking square root on both sides
√(x-3) ^2 = √ 49
X-3 = +7, -7
X = 7 +3, X= -7+3
X = 10 X = -4
So, it has got two solutions
