Answer:
2nd option
Step-by-step explanation:
given an exponential function in the form y = a
to find a and b use the coordinate points it passes through
using (0, 4 ) , then
4 = a [ = 1 ] , that is
a = 4 , so
y = 4
using (2, 100 )
100 = 4b² ( divide both sides by 4 )
25 = b² ( take the square root of both sides )
= b , that is
b = 5
then exponential function is
y = 4 .
B.
You can count all of the ones that have a negative out since they would point down. The opposite of the x value is always in parenthesis. So, B is the correct answer.

Given
Reflection across y-axis
Required
Coordinates of C'
When a point is reflected across the y-axis, the rule is:
So, the reflection on C will be:
