Question

If y = 4x + 3 were changed to y = -4x + 3, how would the graph of the new function compare with the original?

Answer 1

The answer is: it would change orientation and slant down

Explanation:

Hopefully this helps :)

Answer 2

We have the following transformation of functions:
Reflections:
Reflection or turning is the mirror image of a figure. It can also be said that it is the turning of points and graphs around the axes.
To graph y = f (-x), reflect the graph of y = f (x) on the y-axis. (Horizontal reflection)
We have then:
y = 4x + 3
Applying reflection on the y axis:
y = -4x + 3
Answer:
y = -4x + 3 is a horizontal reflection of the original graph y = 4x + 3
