To find the value of y in the given equation, substitute the given value of x to the equation.
y = 4x + 2x² -x³
Substitute 2 for all x's.
y = 4(2) + 2(2²) - 2³ = 8
Therefore, the value of y is 8.

Answer:
option A. 3x - y = 2 and 3x - y = 1
Step-by-step explanation:
Using the rule of y-intercept which is the value of y when x equals 0
<u>Option A:</u> 3x-y=2 and 3x-y=1
y-intercepts will be ⇒ -2 and -1
<u>Option B:</u> 3x+y=2 and 3x-y=1
y-intercepts will be ⇒ 2 and -1
<u>Option C:</u> 3x-y=2 and 3x+y=1
y-intercepts will be ⇒ -2 and 1
<u>Option D:</u> 3x+y=2 and 3x+y=1
y-intercepts will be ⇒ 2 and 1
Comparing the results with the y-intercepts from the graph
From the graph the system of equation intersects with y-axis, (which mean x=0), at y = -2 , -1
So, the system which is represented by the graph is option A
52 years old, its just simple addition haha
