Step-by-step explanation:
The graph shows two linear functions that intersect at (-3,-4).
The blue line is f(x).
At the point of intersection:
....eqn1
The blue line is g(x).
At the point of intersection
....eqn2
Equating both equations we get:
The statement that is true regarding the two functions is that:
Answer: Choice C
=====================================================
Explanation:
The 1/2 out front handles the vertical compression by 1/2. For example, if two points are vertically spaced by 10 units, then their new vertical distance is now (1/2)*10 = 5 units.
The x+3 in the exponent means "shift 3 units to the left". Effectively what's going on is that the old input x is now x+3, ie 3 units larger than before. This shifts the xy axis itself 3 units to the right. If we held the curve fixed in place while the xy axis moved like this, then it gives the illusion the curve is moving 3 units to the left.
Then finally the -2 at the very end shifts the curve down 2 units. This is because whatever the y coordinate is, we subtract 2 from it to do this vertical shifting. For example, the point (0,62.5) shifts 2 units down to (0,60.5)
