If you are given the graph of f, how do you find the graph of f-1?

Step-by-step explanation:

Find points on the original function by looking at the graph and reading the points. Then switch the x- and y-coordinates of each point you read, and plot them. Those are the coordinates of the points of the inverse function.

Step-by-step explanation:

On the same set of coordinates on which f(x) has been graphed, graph the line y = x.  Then reflect the graph of f(x) across the line y = x.

Note that this succeeds only if the graph of f(x) passes the "horizontal line test."  Failure here means that there is no inverse function.

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
