Answer: On this graph, you could label integer points (0,-4) which is the vertex, and (-2, 4) and (2,4)

Step-by-step explanation:

The shape is a parabola opening upwards. The x-intercepts are (-1.414,0) and (1.414, 0) The positive and negative values of √2

The domain (x-values from left to right) All real numbers (-∞, ∞ )

The range (y-values bottom to top) All real numbers greater than or equal to -4 [-4, ∞ )

Need help with 1 & 2 anyone wanna help I will mark you brainliest

1. First step: To get a term of x by itself, add 5 to both sides

Second step: This will become 3x<24

Third step: To separate 3x, divide everything by 3: 3x÷3 < 24÷3

Step four: x < 8

2. First subtract both sides by 12: - 2x + 12 - 12 < - 4 - 12

Second: This becomes - 2x < -16

Third: Divide by -2 to get x by itself - 2x ÷ - 2 > -16 ÷ - 2 Note: If you divide by a negative number, the inequality sign switches. This is a really important step that most students forget.

Fourth: x>8

Note: Try plugging in values when you are done if you are uncertain you have the right answer.
