A polynomial function has roots of -5,2 and 7

sveta [45]

Answer:

P(x) =x³-4x²-31x+70

Step-by-step explanation:

The function is expressed as:

P(x) = (x+5)(x-2)(x-7)

P(x) =(x²-2x+5x-10)(x-7)

P(x) = (x²+3x-10)(x-7)

P(x) = x³-7x²+3x²-21x-10x+70

P(x) =x³-4x²-31x+70

Hence the polynomial is P(x) =x³-4x²-31x+70

Complete the point-slope equation of the line through (-5,4) and (1,6). Use exact numbers.

BigorU [14]

ANSWER

$y - 6 = \frac{2}{7} (x - 1)$

EXPLANATION

The point-slope equation of a straight line is given by:

$y-y_1=m(x-x_1)$

Where m is the slope.

The line goes through (-5,4) and (1,6).

The slope of this line is,

$m = \frac{6 - 4}{1 - - 6}$

$m = \frac{2}{7}$

The point-slope equation is

$y - 6 = \frac{2}{7} (x - 1)$
