Hello I am in third and I have an exercise in math on consider the function f defined on r by:f (x) = 0.5 (x + 1) ²-1.
1. construct an array of values of f for x ranging from -4 to 3 with a step of 1
2. draw in a coordinate system the curve representative of f.
take as unit 1cm on the abscissa axis and 1cm on the ordinate axis
3.Graphically solve f (x)> 2.

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).

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
