Write the equation of the quadratic function in standard form represented by the graph
Nutka1998 [239]
Hello : 
f(x) = <span>a(x-k)²+k....... the point vertex is (h , k )
in this exercice : h = -3 and k = -1    s0 f(x) = a(x+3)²-1
find : a 
but f(0)=8
a(0+3)² -1 = 8
9a-1=8
9a =9
a=1
f(x) =(x+3)²-1 =x²+6x+9-1
f(x) = x²+6x+8    .... (</span><span>the quadratic function in standard form )</span>

Find the slope of the line going through the point (0,3) and (0,4)
telo118 [61]

Answer:

undefined

Step-by-step explanation:

To find the slope of the line between two points, use the slope formula \frac{y_2-y_1}{x_2-x_1}. x_1 and y_1 represent the x and y values of one point the line passes through, and x_2 and y_2 represent the x and y values of another point the line also passes through. Therefore, use the x and y values of the points (0,3) and (0,4) to find the slope. Substitute them into the formula in the right order:

\frac{(4)-(3)}{(0)-(0)} \\= \frac{4-3}{0-0}\\=\frac{1}{0}

However, we can't divide 1 by 0. Therefore, the slope is undefined. (You could also graph the points to see that they form a vertical line, and all vertical lines have an undefined slope.)
