Fox2110which quadratic function is represented by the table? o f(x) -3x2 2x 5f(x) 2x2 -2x 5

Step-by-step explanation:

The value for each value of x is given by f(x) in the table, the quadratic equation which satisfies all the values f(x)  at each value of x is given by:

.

This can be found by substituting all the values of x in the equation and check whether it satisfies the corresponding value f(x) or not.

Therefore, substituting x=-2 in the quadratic equation ,

=

Again, substituting x=-1 in the same equation, we have

=

Putting x=0,

=

Putting x=1,

=

Putting x=2,

=13

Hence, the quadratic equation which is represented by the table is

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
