Help please!!!!!! Giving medals!

Write x2 - 8x + 13 = 0 in the form (x - a)2 = b, where a and b are integers.

(x - 4)2 = 3

(x - 3)2 = 2

(x - 2)2 = 1

(x - 1)2 = 4

Answer 1

a

Answer 2

(x - 4)^2 = 3

Answer 3

Answer 6

Ok thanks :)

The function f(x) = -x^2 - 9x + 10 shows the relationship between the vertical distance of a diver from a pool's surface f(x), in feet, and the horizontal distance x, in feet, of a diver from the diving board. What is a zero of f(x) and what does it represent?

x = 1; the diver jumps in the pool at 1 foot per second

x = 10; the diver jumps in the pool at 10 feet per second

x = 1; the diver hits the water 1 foot away horizontally from the board

x = 10; the diver hits the water 10 feet away horizontally from the board

Answer 7

zero of a function is f(0) =10

Answer 8

So its either B or D?

Answer 9

ya.

Answer 10

D

Answer 11

Alright, thanks! Can you help me with one more?

Answer 12

SURE.GO AHEAD.

Answer 13

What are the zeroes of f(x) = x^2 - x - 2?

x = -2, 1

x = 2, -1

x = -2, -1

x = 2, 1

A polynomial function can be written as (x + 1)(x + 4)(x - 7). What are the x-intercepts of the graph of this function?

(1, 0), (4, 0), (7, 0)

(-1, 0), (-4, 0), (-7, 0)

(1, 0), (4, 0), (-7, 0)

(-1, 0), (-4, 0), (7, 0)
