The graph of the function, ƒ, is shown. Find all numbers, x, such that f(x) = 1.
A) ƒ(1) = 1, ƒ(2) = 1
B) ƒ(−1) = 1, ƒ(2) = 1
C) ƒ(1) = 1, ƒ(−2) = 1
D) ƒ(−1) = 1, ƒ(−2) = 1

The radical equation 2+√2x-3 = √x+7 has a solution set [x= a0} and an extraneous root x = a1.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

Each month, a shopkeeper spends 5x + 14 dollars on rent and electricity. if he spends 3x−5 dollars on rent, how much does he spend on electricity? for which value(s) of x is the amount the shopkeeper spends on electricity less than $100? explain how you found the value(s).
