The parent function of a graph is f(x)=3(2)x Samantha reflected the parent function over the x-axis to get the following function: g(x)=3(2)−x
a. Describe Samantha's error (2 points)

b. Write the correct equation for g(x) after f(x) has been reflected over the x-axis. (2 points)

Part (a)

She replaced x with -x to go from f(x) = 3(2)^x to g(x) = 3(2)^(-x). This will not reflect the graph of f(x) over the x axis. Instead, it will reflect over the y axis. This is because each input is negated from positive to negative, or vice versa. For instance the old input x = 2 becomes the new input -2. Applying this idea to every x input will mirror the curve over the vertical y axis.

Part (b)

The correct equation should be g(x) = -3(2)^x

The negative out front is the same as -1.

We can think of it as g(x) = -1*f(x). The f(x) is the output value, or y value. If we multiply each y output by -1, this will flip every point over the horizontal x axis. A point like (0,3) moves to (0,-3) after doing this operation.

70

step-by-step explanation:

2*5=10

4*15=60

60+10=

70

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
