The y-intercept is where the graph crosses the y-ais, in this case at the point (0, ) or y =. b) What are the -intercept(s)? The -intercept is where the graph crosses the -ais, in this case at the points ( 4, 0) and (4, 0) or = 4 or 4. c) How has this graph transformed from the mother function, f() =? g() is wider than the graph of f() = (which means the quadratic coefficient has an absolute value less than 1). g() is concave down (which means the quadratic coefficient is negative), while f() = is concave up. g() is also shifted units up from f() = (which means the constant term is +). d) Is the average rate of change from = 0 to = 4 negative, positive, zero, or undefined? If we look only at the portion of the graph between = 0 and = 4, we can see that the graph is decreasing. This means that the average rate of change on this interval is negative. e) What is the approimate value of g( 8)? We are looking at the graph where = 8 and trying to determine what the y-value is at that point. We can approimate that g( 8) 6. f) Is g() increasing or decreasing on 4 0?

3 3 The function f () = is graphed below. 3 cont d D) g() = + 3 g() is of the form f( + 3). The constant is being added to the function s domain. This means the parent function will shift to the left or right. Since the constant is positive, it will shift to the left three units. Using this graph as the parent function f(), sketch a graph of each of the following functions. To check this, I could also create a table. 4 3 g() ) g() = + 3 g() is of the form f() + 3. The constant is being added to the function and not to the function s domain. This means the parent function will shift up (since 3 is positive) three units. 3 F.F.3 Match the function with its graph. 1. f () = To check this, I could also create a table g() ) g() = g() is of the form f( ). The domain of is being transformed to. This means the parent function will reflect over the y-ais. To check this, I could also create a table g() D ) g() = g() is of the form f(). The range of the function is being transformed to its opposites. This means the parent function will reflect over the -ais. E To check this, I could also create a table g() F-F.3 Page 3 of 13 M@WUSD 01/15/16

In this case, there is no -intercept, because the eponential function has an asymptote at the line y =. c) What is the average rate of change between = 0 and =? First, if I look at the portion of the graph between = 0 and =, I see that it is increasing, so I know my average rate of change will be positive. I know that I need to evaluate the function at the boundary points. g(0) = 3 and g() = 6. Therefore, I can use the formula for rate of change. g( b) g( a) average rate of change = b a d) Is the function increasing, decreasing, both, or neither?
