Answer:
result is xx/100 - (7/5)x + 49 or.
f−1(x)f −1 (x) = ((x/10) - 7)*((x/10) - 7)
Step-by-step explanation:
for the function f(x)=10(x+7), find f−1(x)f −1 (x)
f-inverse...
x = 10(y + 7)
(x/10) = y + 7
y = (x/10) - 7
f-inverse = (x/10) - 7
then
f−1(x)f −1 (x) =((x/10) - 7)*((x/10) - 7)
xx/100 + 49 - (7/5)x
result is xx/100 - (7/5)x + 49
