Answer:

Plot and connect (5,4), (3,0) and (7,0).

Step-by-step explanation:

This is in factored form and can be graphed directly from the equation. The equation shows the x-intercepts.

The x-intercepts are found by solving for x using the zero product rule.

(x-3)=0 so x = 3

(x-7) = 0 so x = 7

The intercepts are (3,0) and (7,0). Plot the points. The vertex will occur halfway between these points. 7-3 / 2 = 4/2 = 2. This means the axis of symmetry is at x = 5 and this is the x-coordinate of the vertex too.

Substitute x = 5 into the equation and solve for y.

-(5-3)(5-7) = -(2)(-2) = 4

The vertex is (5,4). Plot it and connect the points.

What is the answer to X^2-2X+5=0 rounded to nearest hundreth
eimsori [14]
First you input the equation into the quadratic formula:
                  __________
x=<span><span><span>−<span>(<span>−2</span>)</span></span>±<span>√<span><span><span>(<span>−2</span>)</span>2</span>−<span><span>4<span>(1)</span></span><span>(5)</span></span></span></span></span>
</span>     -----------------------------      
                     2(1)
 Next you simplify the formula:
            ___
 x=<span><span>2±<span>√<span>−16
</span></span></span></span>    ------------
            2

This problem has no real solutions.

Graph the equation using the slope and y-intercept <br> y = 2x - 4
salantis [7]
Put a dot on your y-axis at -4 (the one going up and down), from there go up two, and over one. your second dog should be at (1,-2). connect your dots and that’s your graphed equation !
