im stuck on matching functions to graph with function notation. i dont know what to do. Someone please help.

Since the function notation lets us write f(x) instead of y, the graph of a function f is the set of all points (x, f(x)), where x is in the domain of the function. example Graph f(x) = 5x - 1 and find the value of f(3) by using the graph. The y-intercept is -1 and the slope is 5. When x = 3, y equals 14.

Step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
