Basically you just have to plug in g(x) wherever you see an x in the equation f(x) since x is f(x) you just substitute it . So f(g(x))=2x+3
You then just have to solve for 0
0=2x+3
Subtract 3 from both sides
-3=2x
Divide by 2
X=-3/2
Answer:
(4,7)
Step-by-step explanation:
A number less than or equal to 3 will add one point a 4 will lose two points
Answer:
y + 11 = - 2(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 2 and (a, b) = (- 1, - 1), thus
y - (- 1) = - 2(x - (- 1)), that is
y + 1 = - 2(x + 1)
