Graph this Function 1: f(x) = −3x2 + 2

Mathematics

jasenka [17]4 years ago

I guess that's f(x) = -3x^2+2

Well :

-3x^2+2=0

-3x^2=-2 / : (-3)

x^2= -2/-3

x^2= 2/3 / sqrt

x= +/ - sqrt(2)/sqrt(3)

We got the zero points.

x ~ +/- 0.81

f(0)= -3(0)^2 + 2

f(0)= 2

Mark three points:

(0.81;0)

(-0.81;0)

(0;2)

Connect with parabolic line and ya got a your graph

The slope of a graphed line is -9 and the y-intercept is (0, -2). What is the
timofeeve [1]

Answer:

<h2>y = -9x - 2</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

<em>y = mx + b</em>

<em>m</em> - slope

<em>b</em> - y-intercept (0, b)

We have the slope <em>m = -9</em> and the y-intercept (0, -2) → <em>b = -2</em>.

Substitute:

<em>y = -9x + (-2) = -9x - 2</em>

I need help with Law of Sines; I posted pictures but I need help ASAPP
r-ruslan [8.4K]

Answer:

B = 26.407 degrees

C = 73.593 degrees

c = 30.196 units

Step-by-step explanation:

Use the law of sines

sin(B) / 14 = sin(80) / 31

B = sin-1( sin(80) / 31 x 14)

B = 26.407

C = 180 - 80 - 26.407

C = 73.593

c / sin(73.593) = 31 / sin(80)

c = 31 / sin(80) x sin(73.593)

c = 30.196

Solve 9= 1 + 8x - 8.
insens350 [35]
9 = 1 + 8x - 8

Add 8 to both sides:
17 = 1 + 8x

Minus 1 on both sides:
16 = 8x

Divide both sides by 8
2 = x

Hope it helped :)
