Tell whether { (1,2) (3,4) (4,3) (2,1) } is a function.

Given that (x-3) is a factor of f(x)=x^3+ax^2-x-6, find a and hence the number of real roots or the equation f(x)=0

You have 138.72 in your saving account u take out 45.23 and 18.00 you deposit 75.85 into your account

Will give let f(x)=2x and g(x)=[tex]2^{x}[/tex] graph the functions on the same coordinate plane. what are the solutions to the equation f(x)=g(x) ? enter your answers in the boxes x=[? ] or x=[? ]
