Respuesta :
[tex]a=1 \\ \\ b=-4 \\ \\ c=-5[/tex]
Explanation:
A quadratic function is given by the form:
[tex]f(x)=ax^2+bx+c[/tex]
Where:
[tex]a, \ b \ and \ c \ are \ real \ constant \ and \\ a \ is \ called \ the \ leading \ coefficient[/tex]
By comparing this general rule with our given function:
[tex]f(x)=x^2-4x-5[/tex]
Then we get that:
[tex]a=1 \\ \\ b=-4 \\ \\ c=-5[/tex]

Answer:
Step 1: a = 1, b = -4
Step 2: x = 2, f(2) = -9
Step 4: (5,0) and (-1,0)
Step 6: f(0) = -5
On the graph the points plotted are (-1,0) , (0,-5) , (2,-9) , and (5,0)
