first off, let's notice the parabola is a vertical one, therefore the squared variable is the x, and the parabola is opening upwards, meaning the coefficient of x² is positive.
let's notice the vertex, or U-turn, is at (-2, 2)
Answer:
(4, –2, 1)
Step-by-step explanation:
You have to put in it the calculate and solve the matrix way
Answer:
4,000 L/h
Step-by-step explanation:
First we'll find the amount of the change.
18,000 - 6,000 = 12,000 L
The time of the volume change was 3 hours: 0230 - 0530
Since we're looking for liters per hour, we will divide the liters (12,000) by the hours (3)
12,000/3 = 4,000 L/h
Answer:
C
Step-by-step explanation:
The slope m of the functions give the measure of the rate of change.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
g(x) = x - 3 ← is in slope- intercept form
with slope m = = 2.5
Calculate the slope of f(x) using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, - 3.5) and (x₂, y₂ ) = (1, - 1) ← 2 points from the table
m = = 2.5
Hence
The slopes of g(x) and f(x) are both m = 2.5, thus
The functions increase at the same rate → C
