The vertex of a parabola is at (-2,4), and the x-intercepts are at -6 and 2. determine the domain and range of the function. a. d. all real numbers r: all real numbers c. d. all real numbers r: y ≤ 4 b. d.-6 ≤ x ≤ 2 r: y ≤ 4 d. d. x ≤ 4 r: all real numbers

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
