Answer:
f(x)=0.333*(1*x+-4)*(1*x+1)
Step-by-step explanation:
<u>Your exercise:</u>
Find a quadratic function with roots at 4 and -1 whose graph goes through the point -2 .
The function f(x)=a*(1*x+-4)*(1*x+1) has the desired roots.
Insert the point (1, -2) to find a.
-2=a*(1*1+-4)*(1*1+1)
-2=1*a*(1*1+-4)*(1*1+1) (add 1 to -4)
-2=1*a*-3*(1*1+1) (add 1 to 1)
-2=1*a*-3*2 (Multiply -3 by 2)
-2=1*-6*a (Swap both sides of the equation.)
-6*a=-2 : (-6)
1*a=0.333
f(x)=0.333*(1*x+-4)*(1*x+1)
