Question

Which of the following represents the graph of f(x) = 3x + 1? graph of exponential rising up to the right, through the point 0, 0 graph of exponential rising up to the right, through the point 0, 1 graph of exponential rising up to the right, through the point 0, 2 graph of exponential rising up to the right, through the point 0, negative 2

Answer 1

Graph of exponential rising up to the right, through the point (0, 2).

Explanation:

I think you mean f(x) = 3^x + 1.

When x = 0, 3^x = 1, so the graph of f(x) = 3^x will rise up to the right and pass through point (0. 1)

The + 1 translates the graph up 1 unit so

The graph of f(x) = 3^x + 1 passes through the point (0, 2).
