Help me please
Answer all of them

Answer 1

Explanation:

h(x) = -(x + 11)² + 1

1.

the "zeroes" of a function are the values of x that create 0 as result.

so,

0 = -(x + 11)² + 1

(x + 11)² = 1

x + 11 = ±1 | as (+1)² = (-1)² = 1

x + 11 = 1

x = -10

x + 11 = -1

x = -12

smaller x = -12

larger x = -10

2.

the vertex of the parabola can be seen directly in the vertex form of the parabola equation, as it was given to us :

y = a(x - h) + k

(h, k) is the vertex.

so, in our case,

the vertex = (-11, 1)
