If f(x)=4x2=1 and g(x)=x2-5, find (f-g)(x)
a: 3x2+6
b: 5x2-6
c: 3x2-4
d: 5x2-4

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
