Within one hour of working at Starbucks, there are a total of 17 customers, each purchased either a Venti sized coffee ($5)
and a Grande sized coffee ($4). If the store earned a total of $75
within that one hour, find the numbers of Venti and Grande
coffee sold.

Which is the graph of the piecewise function f(x)? f(x)=[tex]f(x) = \left \{ {{-x+1, x\leq 0 } \atop {x+1, x\ \textgreater \ 0}} \right.[/tex]

What is the average rate of change for this function for the interval from x=2 to x=4 ?

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
