Solve for x in the first equation:
X -2 = 1/3
Add 2 to both sides:
X = 2 1/3
Now replace x in the second equation:
2 1/3 ^2 - 4(2 1/3) + 4
5 4/9 - 9 1/3 + 4 = 1/9
Answer is B.
Given data:
The given expression is 14=X-3
The given expression can be written as,
14+3=X
X=17
Thus, the value of X is 17.
Part A:
Yes it is a function. Every input value only has one output value
Part B:
If you look in the table, when x =3, y=6.
When you plug 3 into the equation (4*3+8) you get 20. Therefore f(x) is greater.
Part C:
Plug in again.
76 =4x+8
68=4x
17=x
