Figure 3 shows a sketch of part of the curve C with equation Y=x(x+ 4)(x - 2)
The curve C crosses the x-axis at the origin and at the points A and B.
(a) Write down the x-coordinates of the points A and B.

Step-by-step explanation:

because The curve C crosses the x-axis at the origin and at the points A and B =>  the x coordinates of A and B are the solution of the equation:

 x(x + 4)(x - 2) = 0

<=> x = 0

      x = -4

      x = 2

because the x-coordinates of the points A and B aren't 0 and the x-coordinate

of A is a negative value

=>  the x-coordinate of  A is -4

the x-coordinate of B is 2

the answer is 5636.7

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
