For the function f (x) = 10 (x+7), find f-1 (x) f - 1 (x)

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
