Write an equation of a polynomial with the given characteristics: a quadratic function has x -intercepts of -3 and 1, and a y-in

fredd [130]

Answer:

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

Step-by-step explanation:

x = -3 & 1; f(x) = 9

f(x) = a(x-r1)(x-r2)

f(0) = a(x-r1)(x-r2) = 9; 9 = a(0-(-3))(0-1)

9 = a(3)(-1); 9 = a(-3)

a = -3

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

IL<br> 8x-9<br> 5x-3<br> What’s x

shepuryov [24]

Step-by-step explanation:

8x-9=5x-3

Move any equation to the opposite side. I'll use the left this time

$8x - 8x - 9 + 9 = 5x - 8x - 3 + 9$

$0 = - 3x + 6$

move 6 to opp side

$- 3x = - 6$

$\frac{ - 6 = - 3x}{ - 3}$

$x = 2$
