This can be done in two ways
One method is to check the answer options in both f(x) and g(x) and select the one that matches for both.
The second is to form a quadratic equation and solving as such:
f(x) = g(x)
-x² + 4x + 12 = x + 8
x² - 3x - 4 = 0
(x - 4)(x + 1) = 0
x = 4; x = -1
Only x = 4 is given in the options, so the answer is B

Graph y equals 1/2 x - 3​
Elis [28]

Answer:

Resulting plot in the image attached

Step-by-step explanation:

Start by making a table of (x,y) pairs that satisfy this equation. Notice that two pairs would be enough, but it is always safer to obtain at least three to see them actually "aligned".

We are trying to find values for y when x= 0, 2, and 4 to make our calculations simple:

y=\frac{1}{2} x-3

When x = 0 then: y=\frac{1}{2} (0)-3=-3 So we plot the value (0,-3) on the x-y plane.

When x = 2 then: y=\frac{1}{2} (2)-3=1-3=-2 So we plot the value (2,-2) on the x-y plane.

When x = 0 then: y=\frac{1}{2} (4)-3=2-3=-1 So we plot the value (4,-1) on the x-y plane.

Please see the points and the resulting line in the image attached
