Provide an appropriate response.The graph of an exponential function with base a is given. Is a > 1 or is 0 < a < 1? Explain how you arrived at your answer. Give the domain and range of f. f(x) = ax 
What will be an ideal response?
a > 1, because if a > 1, then a2 > a, domain = (-?, ?), range = (0, ?)

Translate the sentence to an equation using the variable x. Then solve the equation.If 5 times a number is added to -4, the result is equal to 9 times the number.
A. 5x + (-4) = 9x; -1 B. 9(5x - 4) = -4; -1 C. 5x + 4x = 9; 1 D. 5x - (-4) = 9x; 1
