Question

Determine which graph represents a reflection across the x-axis of f(x) = 3(1.5)x.

Answer 1

Answer:

Option 2 is graph after reflection across x-axis.

Step-by-step explanation:

We have been given the function:

$f(x)=3(1.5)^x$

We have reflection rule along x-axis as:

$(x,y)\rightarrow (x,-y)$

Hence, the given function when reflected across x-axis becomes:

$-y=3(1.5)^x$

$y=-3(1.5)^x$

You can see the attachment for the graph of the function after reflection in the attachment.

Option 2 is graph after reflection across x-axis.

Answer 2

SECOND!!!!! Its the second one :)
