Answer:
D) It would move to the right 3.
Step-by-step explanation:
Given : If you subtracted 3 from the exponent in an exponential function,
To find : what would happen to the graph
Solution : We have given that exponential function
If we subtract 3 from power of exponent
Let parent function is
Transformed function is
By the Transformation rule f(x) →→f (x -h) it tell that graph of f(x) would shift right by h unit.
Hence , graph of would shift right by 3 unit.
Therefore, D) It would move to the right 3.

Answer:
x = 3
Step-by-step explanation:
Square both sides of the equation
(x - 3)(x - 5) = 0
x = 3 or 5
Now, you must always check your results because a result may not satisfy the original equation.
If x = 3, then and 3 - x = 3 - 3 = 0
So 3 satisfies the original.
If x = 5, then , but 3 - x = 3 - 5 = -2. Therefore, 5 does NOT satisfy the original equation.
That means that x = 3 is the solution to the equation.
