Use the exponential regression equation that best fits the data (2,7)(3,10)(5,50)(8,415) to estimate the value of y when x equals seven

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*

Solution: x2+4x=276x=27,x=9/2answer: no
