How many roots do u thinn

Mathematics
1 answer:
hram777 [196]2 years ago
6 0

Answer:

  • 2 roots
  • 1 root

Step-by-step explanation:

Each equation is in vertex form, so you can easily determine the number of real roots. The leading coefficient tells you whether the parabola opens upward (positive) or downward (negative).

  y = a(x -h)^2 +k

has leading coefficient "a" and vertex (h, k).

__

<u>f(x) = 1/3(x +5)^2 +7</u>

  vertex: (-5, 7), opens downward

The vertex is above the x-axis, so there are two real roots.

__

<u>f(x) = -5(x -3)^2</u>

  vertex: (3, 0), opens downward

The vertex is on the x-axis, so there is one real root.
