Question

The point (1, 4) is on the graph of y = f(x). What are the coordinates of the map of this point on the graph y = 4f(x)?

Answer 1

Answer:

Step-by-step explanation:

As per the question:

y=f(x) where x=1 & y=4  {This is being taken from the question itself.}

Putting the values in above.

4=f(1)  { Let's consider this as "A"}

y = 4 * f(x)

To plot the coordinates of this point, we have to consider x = 1

From A, we can see that f(1) = 4

So,

y = 4 * f(1)

y = 4 * 4

y = 16

New coordinates are (1,16)

x = 1 & y = 16.
