In parts af use the given figure Solve fx 6 Solve fx 15 So

In parts (a)-(f), use the given figure. Solve f(x) = 6. Solve f(x) = 15. Solve f(x) = 0. Solve f(x) greaterthan 6. Solve f(x) lessthanequal 15. Solve 0 lessthan f(x) lessthan 15. For what value of x does f(x) = 6? x = For what value of x does f(x) = 15? x = For what value of x does f(x) = 0? x = For which values of x is f(x) greaterthan 6? For every x in the interval f(x) greaterthan 6. (Type your answer in interval notation.) For which values of x is f(x) lessthanequal 15? For every x in the interval Q, f(x) 15. (Type your answer in interval notation.) For which values of x is 0 lessthan f(x) lessthan 15? For every x in the interval, 0 lessthan f(x) lessthan 15. (Type your answer in interval notation.)

Solution

The points are (-18,0) , (18,6) and (72,15)

a) for f(x) =6 , is for x= 18

b) for f(x)=15 , is for x=72

c) for f(x)=0 , is for x=-18

d) f(x) >0 , for interval (18,infinity)

e) f(x) <=15 for interval (-infinity, 72]

f) 0<f(x) <15 for interval (-18,72)
