Find the value of x in the isosceles triangle shown below. A. x = 4
B. x = 12
C. x = √640
D. x = 8

The graph below could be the graph of which exponential function?

Prove that 3: 8 is equivalent to 12: 32.a. use diagrams to support your answer.

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above
