Answer:
Step-by-step explanation:
From inspection, the curve has 3 turning/stationary points, which suggests it is quartic function. In factored form: ax(x + b)(x + c)(x + d)
From inspection, there are 3 roots at: 
Therefore x, (x + 2) and (x - 1) will be factors.
Whenever a turning/stationary point touches the x-axis, we conclude that a root is repeated at that point. Therefore, from inspection, root x = 1 is a repeated root. So x, (x + 2) and (x - 1)² are factors.
The quartic curve is a "n" shape, which means the leading coefficient is negative. We are told the leading coefficient is + or - 1. Therefore, it will be -1.
Therefore, an equation for the function in factored form is:
Answer: The answer to your question will be -
5^√16x^4
The distance between any point (x0,y0) on the parabola and the focus (m,n) is the same as the distance between (x0,y0) and the directrix line ax+by+c. The distance between (x0,y0) and focus (a,b) is \sqrt((x-m)^2+(y-n)^2). The distance between (x0,y0) and ax+by+c is |ax0+by0+c|/\sqrt(m^2+n^2). Equalize these two expressions.
Answer:
The statement is true.
Step-by-step explanation:
Given : Reflecting the graph of y = sin x across the y-axis is the same as reflecting it across the x-axis.
To find : Is this statement true or false?
Solution:
Rules of reflection :
Along across y-axis if we have a point
So, y=sinx
The reflection across y-axis→ .......[1]
Along across x-axis if we have a point
so, y=sinx
The reflection across x-axis → .....[2]
Hence, [1] and [2] both of them are equal
Therefore, the statement is true.
Answer:
y=1/2x -5
because it starts at -5 on the y axis and goes up 2 squares and over 1 square
