Answer:
_______
Step-by-step explanation:
i cant read that sorry :|
y = x^2 + 2x...eqn 1
y = 3x + 20...eqn 2
subst for y in eqn 1...
=> x^2 +2x = 3x +20
=> x^2 - x - 20 =0
=> (x-5) (x+4) =0
=> x = 5 or -4
for x =5, y = 35 (sub for x in eqn 1 or 2)
for x = -4, y = 8 (sub for x in eqn 1 or 2)
First graph is the correct one.
when x= 1
y=f(x) = -√1 = -1
when x= 2
y= -√2
