Make a table of values for the function rule. then graph the function. y=-x²+4

lakkis [162]

Answer:

check the attached picture

Step-by-step explanation:

Given function is $y=-x^2+4$ .

Now we need to make a table of values for the function rule then graph the function.

We are free to plug any values of x like -3,-2,-1,0,1,2,3,... etc becaues domain of polynomial function is all real numbers.

Let's plug x=1 into given function to find the y-value

$y=-x^2+4$

$y=-(1)^2+4$

$y=-1+4$

$y=3$

Hence the first point is (1,3).

Same way we can find few more points to complete the table then graph those points and connect them to get the final graph.

Does anyone know how to do this??

Fynjy0 [20]

Answer:

y > 11/2

Step-by-step explanation:

This is solved the same way a 3-step equation is solved.

Step 1: subtract the smaller variable term from both sides.

4y -2y +3 > 2y -2y +14

2y +3 > 14

Step 2: subtract the constant with the variable term.

2y +3 -3 > 14 -3

2y > 11

Step 3: divide by the coefficient of the variable.

2y/2 > 11/2

y > 11/2

_____

Additional comment

By choosing to subtract the smaller variable term in the first step (regardless of which side of the inequality it is on), we ensure that the remaining variable coefficient is positive. That means we can do step 3 without worrying about changing the direction of the inequality symbol, because we're dividing by a positive number.
