Question

on a piece of paper, graph f(x) = 2 • (3)^x. then determine which answer choice matches the graph you drew

Answer 1

Answer: B= Graph B

Step-by-step explanation:

Answer 2

I would make a table and plug in values for "x" in the equation to find f(x) or y

x = 0

$f(x)=2*(3)^x$

$f(0)=2*(3)^0$(there is a rule that when the exponent is 0, the result is 1)

$f(0)=2*1$

f(0) = 2                   (0,2)

x = 1

$f(x)=2*(3)^x$

$f(1)=2*(3)^1$

$f(1)=2*3$

f(1) = 6        (1,6)

You could do more points.

But these two points shows that the y-intercept (the y value when x = 0 or (0,y)) is 2, and that the graph is increasing.

Your answer is B
