Answer:
Graph (2), top right.
Step-by-step explanation:
Given function is f(x) = x² + 2x - 1
f(x) = x² + 2x + 1 - 2
f(x) = (x + 1)² - 2
From this standard equation of a parabola,
Vertex → (-1, -2)
Axis of symmetry → x = (-1)
y-intercept → y = (-1)
Since coefficient of maximum degree term (x²) is positive so, parabola is opening upwards.
From the given choices, second option (top row right) is the answer.
Answer:
To order decimals, you first need a range of values.
Step-by-step explanation:
For example, if there are 5 values: 0.25, 0.87,0.19,0.89 and 0.98
First, look at the first digit after the decimal. The smallest digit is the smallest so far. In this case, it is 0.19 as '1' was the smallest digit. Second would be 0.25 because 2 is the second smallest digit here.
Now, we have 3 remaining numbers: 0.87, 0.89 and 0.98
You can notice that both 0.87 and 0.89 have the same first digit after the decimal.
Do fix this problem, look at the second digit and decide the smallest one. In this case, it is 0.87.
This means the order will go like this if it is smallest to largest: 0.19, 0.25, 0.87, 0.89, 0.98.
If it is largest to smallest, do it the other way around.
Hope this helped!
