I need help on this question
1 answer:
Hi!
The line of symmetry is a line that has equal parts of the shape on both sides of it.
Look at the shape. Is there a place where you can put a line that divides it in half? Or will one part of it still be unequal?
I included an image that shows the line of symmetry. Note how the halves of the triangle on both sides of the line are equal.
The line of symmetry is x = 3
Hope this helps! :)

The given function f(x) is:
And the other given function g(x) is:
g(x) in comparison with f(x) has the next transformation:
1. g(x)=f(bx): g(x)=3(0.1x)+5. This is a horizontal stretch: the x-coordinates will change as:
This is the graph of both functions:
The red-one is f(x) and the blue-one is g(x).
Then for example when the coordinates of f(x) are (1,8) for g(x) the coordinates will be:
Then, the slope of f(x) has a greater value than the slope of g(x), since the change on the x-axis is bigger in the g(x) graph for the.
