The original price is $68.26 I think lmk if I’m wrong:)
Answer:
(-1,-18) is the coordinate of the vertex.
Step-by-step explanation:
We can obtain the vertex by taking the derivative and equating it to zero. I know this because the the slope of the tangent line at the vertex has to be equal to zero.
the derivative would be 4x + 4 = 0, where x = -1.
Plugging x into the original value we will end up with the y coordinate.
Hope this helps.
Well on a table of data, if the y coordinates increase a lot over a short x distance then it will be steep.
In an equation, you would put it into y = mx + b form and whatever your m is will be your slope. If m is large, it will be steep.
55,57,59
Let the smallest integer = x
171= (x) + (x+2) + (x+4)
171= 3x + 6
3x = 165
x= 55
therefore the integers are 55, 57, 59
