What's the full equation for this graph?
swat32
1.
Left side of a graph is a line that passes through points A=(-1,-1) and B=(1,4) so we can write its equation as:

(y-y_A)=\dfrac{y_B-y_A}{x_B-x_A}(x-x_A)\\\\\\
\big(y-(-1)\big)=\dfrac{4-(-1)}{1-(-1)}\big(x-(-1)\big)\\\\\\
y+1=\dfrac{4+1}{1+1}(x+1)\\\\\\y+1=\dfrac{5}{2}(x+1)\\\\\\y+1=\dfrac{5}{2}x+\dfrac{5}{2}\\\\\\y=\dfrac{5}{2}x+\dfrac{5}{2}-1\\\\\\\boxed{y=\frac{5}{2}x+\frac{3}{2}}

2.
Right side of a graph is a parabola with vertex V=(3,-3) that passes through point P=(1,1). Its equation:

y=a(x-x_V)^2+y_V\\\\y=a(x-3)^2+(-3)\\\\y=a(x-3)^2-3

Substitute x=1 and y=1 to calculate parameter a

1=a(1-3)^2-3\\\\1=a(-2)^2-3\\\\1=4a-3\\\\4a=4\quad|:4\\\\a=1

and we have the equation of parabola:

y=a(x-3)^2-3\\\\y=1\cdot(x-3)^2-3\\\\y=(x-3)^2-3\\\\y=x^2-2\cdot x\cdot3+3^2-3\\\\y=x^2-6x+9-3\\\\\boxed{y=x^2-6x+6}

From 1. and 2. full equation for graph is:

f(x)=\begin{cases}\dfrac{5}{2}x+\dfrac{3}{2}\qquad\text{for}\,\,\,x\ \textless \ 1\\\\x^2-6x+6\qquad\text{for}\,\,\,x\geq1\end{cases}

Answer:

mnt should be 120 degrees because 35 + 25 = 60 and 180 - 60 is 120 ( the triangles are a mirrored image of each other because the line lengths are the same)
