Write an exponential function that passes through (0,256) and (4,81)

Why did the ice arena get so hot after the big game (this is math related google it to find the paper

The graph shown is the graph of which function?

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
