The number inside parenthesis is the x value.

Look up the provided X value and see what the corresponding Y value is, which would be the answer.

In the given table when X is 5, the f(x) = -8

Answer:

The correct option is 1. The value of f(5) is -8.

Step-by-step explanation:

In the given table the first column represents the values of x and the second column represents the values of function f(x) at difference values of x.

From the given table it is clear that

The value of function is -2 at x=-4. It means f(-4)=-2.

The value of function is 5 at x=-1. It means f(-1)=5.

The value of function is 4 at x=3. It means f(3)=4.

The value of function is -8 at x=5. It means f(5)=-8.

The value of f(5) is -8. Therefore the correct option is 1.

The lesser of two consecutive even integers is 10 more than one-half the greater. Find the integers.
1st: 2x
2nd: 2x+2
-----
EQUATION:
2x =(1/2)(2x+2)+10
2x = x + 11
x = 11

1st: 2x = 22
2nd: 2x + 2 = 24

1st: x
2nd: x+1
3rd: x+2

AleksAgata [21]

Answer:

y=-2x+8

Step-by-step explanation:

y-y1=m(x-x1)

y-4=-2(x-2)

y-4=-2x+4

y=-2x+4+4

y=-2x+8
