a) 1
b) 5
c) 3
Explanation:
To determine the number of solutions in a polynomial, wewould use the degree of the polynomial.
a) y = -6x - 9
The degree of the polynomial is linear (the highest degree is one)
Hence, it has one solution
[tex]b)\text{ }y=2x^5-x^4+2x^3-6x^2+2x+4[/tex]The degree of the above polynomial is quintic (highest degree is 5)
Hence, it has 5 solutions
[tex]c_{})\text{ }y=-4x^3-10x^2+7x+5[/tex]The highest degree above is 3. The polynomial is cubic.
Hence, it has 3 solutions
