Answer:
a, c
Step-by-step explanation:
The vertex is at x=1 and the parabola opens downward, It is increasing for all values of x < 1, and decreasing for all values of x > 1.
The answer choices divide the increasing interval into two parts:
x < 0 . . . . . . . 1st choice
0 < x < 1 . . . . 3rd choice
Answer:
Step 1: 14x − 21 = 1; Step 2: 14x = 22
Explanation:
7(2x−3)=1
Step 1: Simplify both sides of the equation
7(2x−3)=1
(7)(2x)+(7)(−3)=1(Distribute)
14x+−21=1
14x−21=1
Step 2: Add 21 to both sides
14x−21+21=1+21
14x=22
Step 3: Divide both sides by 14
14x / 14 = 22 / 14
x = 22 / 14: x = 11/7
