Multimedia Practice What is the graph of the equation y2x + 47) which means the line crosses the y-axis at the Pot this point 5 from left to right of the line is positive, so it goes 2 and then move right pintercept Move up 2 2. now at the point ). Plot this point Da line to connect the two points

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

hm let me think hm think think hm think yes

the answer is d

step-by-step explanation:

you can also use mathway to get you answer + steps

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
