Use function notation to write the equation of the line

1 answer:

8 0

(-4,4),(0,-2)
slope = (-2 - 4) / (0 - (-4) = -6 / 4 = -3/2

y = mx + b
slope(m) = -3/2
use either of ur points...(0,-2)...x = 0 and y = -2
now sub and find b, the y int
-2 = 0(-3/2) + b
-2 = b
so ur equation for this line is : y = -3/2x - 2

to turn it to function notation, sub in f(x) for y
f(x) = -3/2x - 2 <=== ur answer

G find the domain for the particular solution to the differential equation dy dx equals the quotient of negative 1 times x and y

faust18 [17]

$\frac{dy}{dx} = \frac{-x}{y}$
by separating the variables
∴ y dy = -x dx
integrating both sides with respect to x
∴ ∫y dy = ∫-x dx
∴ $\frac{ y^{2} }{2} = - \frac{ x^{2} }{2} +c$
finding c using initial condition y(2) = 2.
∴ $\frac{ 2^{2} }{2} = - \frac{ 2^{2} }{2} +c$
∴ c = 4
∴ $\frac{ y^{2} }{2} = - \frac{ x^{2} }{2} +4$
multiplying all the equation by 2
∴ y² = -x² + 8
∴ x² + y² = 8
The resultant equation represents the equation of the circle
with center (0,0) and radius = √8 = 2√2
so, the domain of this function is [-2√2 , 2√2]
