One factor of the function f(x) = x3 − 8x2 + 17x − 10 is (x − 5). Describe how to find the x-intercepts and the y-intercept of t
kozerog [31]

Answer:

x-intercepts: (1,0), (2,0), (5,0)

y-intercepts: (0,-10)

Step-by-step explanation:

One factor of the function f(x) = x^3-8x^2 + 17x-10 is (x-5).

Factor the polynomial in the following way:

x^3-8x^2 + 17x-10\\ \\=x^3-5x^2-3x^2+15x+2x-10\\ \\=x^2(x-5)-3x(x-5)+2(x-5)\\ \\=(x-5)(x^2-3x+2)

Now factor the quadratic in brackets:

x^2-3x+2\\ \\=x^2-2x-x+2\\ \\=x(x-2)-(x-2)\\ \\=(x-2)(x-1)

Hence,

f(x)=(x-5)(x-2)(x-1)

The x-intercepts are points at which y = 0, so

(x-5)(x-2)(x-1)=0\\ \\x-5=0\ \text{or}\ x-2=0\ \text{or}\ x-1=0\\ \\x=5\ \text{or}\ x=2\ \text{or}\ x=1

The y-intercepts are points at which x = 0, so

y=0^3-8\cdot 0^2+17\cdot 0-10=-10

Please help me with math !!
Setler [38]

Answer:

  • a) x = 4
  • b) y = 1.25x + 15
  • c) (-12, 0)

Step-by-step explanation:

a) PQ is parallel to the y-axis and contains point (4, 5).

<u>It means its equation is:</u>

  • x = 4

b) RQ is parallel to OP.

Parallel lines have equal slopes.

<u>Find the slope of OP:</u>

  • m = 5/4 = 1.25

RQ has slope of 1.25 and passes through (- 8, 5).

<u>Find its equation using point-slope form:</u>

  • y - 5 = 1.25(x - (-8))
  • y - 5 = 1.25x + 10
  • y = 1.25x + 15

c) <u>The x-intercept is determined at y = 0:</u>

  • 0 = 1.25x + 15
  • 1.25x = - 15
  • x = - 15/1.15
  • x = - 12
