Answer

Which point is on the graph of f(x) = 4^x?

Solution

The question is asking which point lies on the graph of the function f(x)=4xf(x) = 4^x.

To determine which point is on the graph, let's check the values of f(x)=4xf(x) = 4^x for the xx-values in the given options:

  1. Option A: (0, 0) f(0)=40=1(not equal to 0)f(0) = 4^0 = 1 \quad \text{(not equal to 0)} So, (0,0)(0, 0) is not on the graph.

  2. Option B: (0, 4) f(0)=40=1(not equal to 4)f(0) = 4^0 = 1 \quad \text{(not equal to 4)} So, (0,4)(0, 4) is not on the graph.

  3. Option C: (1, 4) f(1)=41=4f(1) = 4^1 = 4 This matches the point (1,4)(1, 4). So, this point is on the graph.

  4. Option D: (4, 1) f(4)=44=256(not equal to 1)f(4) = 4^4 = 256 \quad \text{(not equal to 1)} So, (4,1)(4, 1) is not on the graph.

The correct answer is Option C: (1, 4).

Tip:

In exponential functions of the form f(x)=axf(x) = a^x, as xx increases, the function grows rapidly for a>1a > 1, and the graph has a horizontal asymptote at y=0y = 0.
