Which is a valid prediction about the continuous function f(x)?
a. f(x) ≥ 0 over the interval [5, ∞).
b. f(x) ≤ 0 over the interval [–1, ∞).
c. f(x) > 0 over the interval (–∞, 1).
d. f(x) < 0 over the interval (–∞. –1).

the bolded word " farsighted" could be replaced with visionary.

idk

step-by-step explanation:

a.for lorena 14 hours makes $126   for 16 hours she makes 144

for julie 6 hours makes $72 for 21 hours its $252

b. julie makes more money than lorena julie makes $12 an hour and lorena makes $9  

.

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
