What are the vertex and x-intercepts of the graph of the function below? y =(x + 4)(x - 2)

Answers

Answer 1

Answer: y = (x + 4)(x - 2)

The x-intercepts:

0 = x + 4
0 = x - 2

x = -4
x = 2

The vertex:

y = (x + 4)(x - 2)
y = x^2 + 2x - 8
x = -b/2a
If ax^2 + bx + c, then:
a = 1
b = 2
c - 8
x -2/2(1)
x = -1
y = (-1)^2 + 2(-1) - 8
y = -9

The vertex is (-1, -9)
The x-intercepts are -4 and 2

Answer 2

Answer:

Answer: vertex: (1,-9); intercepts: x=4,-2

Which expression is equivalent to 10 - 810−810, minus, 8?

Answers

Answer:

10+(-8)

Step-by-step explanation:

Final answer:

The expression 10 - 8 - 810 is equivalent to -808.

Explanation:

The expression 10 - 8 - 810 is equivalent to subtracting 8 from 10 and then subtracting 810. The order of operations states that subtraction should be done from left to right, so we first subtract 8 from 10 to get 2. Then we subtract 810 from 2 to get -808.
