Answer:
discriminant(∆) = 0
vertex and intercept labeled on the graph below
NOTE: the x-intercept is the vertex
Step-by-step explanation:
Comparing [tex]y = 25x^{2} - 30x + 9[/tex] with [tex]y = ax^{2} − bx + c[/tex]
Thus,
a=25 b = -30 and c = 9
[tex]discriminate (d) = b^{2} - 4ac\\d = (-30)^{2} - 4(25)(9)\\[/tex]
the ' - ' when squared becomes '+'
d = 900 - 900
d = 0
Thus, the value of discriminant(∆) is 0
