SOMEBODY HELP

Hi there!

For this, we are given a set of equations which is then equal to f(x), a function based off an input x. This means that we can correspond x to the input and f(x), or what the functions are equal to, to the output.

This means we can essentially just try inputs into the equations, and see if the output matches:

x * 5 - 11:

2  * 5 - 11 = 10 - 11 = -1, not the output, thus this isn't the equation.

x^3 + 3:

2 ^ 3 + 3 = 8 + 3 = 11

3 ^ 3 + 3 = 27 + 3 = 30

4 ^ 3 + 3 = 64 + 3 = 67

5 ^ 3 + 3 = 125 + 3 = 128

As we can see, all of these inputs and outputs match, this means that this equation is the correct one. Therefore, your answer is the second choice, x^3 + 3.

Hope this helps!

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
