Use the graph of the exponential growth function f(x) = a(2x) to determine which statement is true. f(0) = 2 when a =1/2 . f(0)

Kryger [21]

Math symbols were invented for a reason. They help communicate your intent. Here, it looks like you may intend

... f(x) = a(2^x)

When x=0, this will have the value "a". When x=1, this will have the value a^2. The appropriate selection is

... f(0) = 3 when a = 3

Which inequality represents all values of x for which the quotient below is<br> defined?

garri49 [273]

Answer:

Option B: x > 0

Step-by-step explanation:

Option A is wrong because $\sqrt{3(0)}$ will be 0. So, the inequality can't be divided by 0.

Option C is wrong because 1 will suffice this inequality. $\sqrt{7}/\sqrt{3}=1.5 (approx)$

Option D is wrong because any value in the root has to be greater or equal to 0 (otherwise, it's imaginary number). -1 will give the latter root a value of root-(-3).

Leaving us with only option B, which is the right answer.
