"A parabola is curved instead of linear, in your case it is probably just facing up or down so I won't get into square roots for now.So the quadratic equation that you probably have had to memorize (or will soon) is:
x=(-b[+or-]√(b²-4ac))/2a when you have an equation like ax²+bx+c=0Now where does the curve shape come from? You see that little pesky plus or minus in the equation? That's because there are always 2 values (inputs) that will generate the same output. Example:y=x²(2)²=4(-2)²=...4So if you were to follow this pattern, and plot the points on a graph, you would end up with a curve. You end up with a curve because the slope is constantly increasing.
And this is actually where you start the study of Calculus(!), which is all about measuring slopes (And a bunch of other stuff, but this is the easiest part to explain). Actually, in this case of y=x², the slope at any given point (funnily enough) is equal to 2 times your x-value.
The point is, your line is curved because unlike a linear equation, the slope is changing (at a constant rate)."
Answer:
D
Step-by-step explanation:
The red graph is vertically shifted from the blue graph. Let's understand horizontal and vertical shifts.
If we have a graph of 
, then
- f(x) + a is a units shifted vertically up
- f(x) - a is a units shifted vertically down
- f(x-b) is b units shifted horizontally right
- f(x+b) is b units shifted horizontally left
Since the red one is vertically shifted 3 units up (compared to blue graph), the equation would be:
Correct answer is D
Answer:
B
Step-by-step explanation:
if there are 6 flowers in each vase and there are 2 vases that means there is 12 flowers. 12 divided by 3 =4
