I need Help on 2 questions, one has multiple parts please
5. Graph the function
F(x)= {3. If -infinity {1/3x+3 If -2>x> infinity.
(Not sure what x is)
10. Consider the following piecewise-defined function, and make observations about its graph. It’s a 10 by 10 so it goes from positive 10 to negative 10.
There is a closed point on (-9,-5) and a hump shape leading to an open point on (-3,-5) there’s a line connecting it to another open point on (1,-9,) then there is a continuous line going from (1,-9) to (10,0) and continuing. There is another closed point at (1,0) there is nothing connecting this point to ANY of the others.
Part A: Over what interval(s) is the function increasing?
Part B: Over what interval(s) is the function decreasing?
Part C: What is the domain of the function?
Part D: what is the range of the function?
Part E:Does the graph represent a function? Explain how you know.
Part F: is this piecewise function continuous?

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

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!
