Which is the polynomial function of lowest degree with leading coefficient of 4 and roots 7 and 3?
1 answer:
Answer:
Step-by-step explanation:
If the roots are 7 and 3, then x = 7 and x = 3 are solutions. In factor form, x = 7 is (x - 7); in factor form, x = 3 is (x - 3). We FOIL these together to get
which simplifies to
and we distribute in the 4:
to get
which is another way to write the last choice you're given.

Yes, you're right! The first step is rewriting the equation as
Subtract from both sides:
Use the property to rewrite the equation as
Divide both sides by
Alternative strategy:
Consider both sides as exponents of e:
Use to write
Divide both sides by a:
Consider the logarithm base b of both sides:
The two numbers are the same: you can check it using the rule for changing the base of logarithms
