Hubba Bubba Bubble gum was $0.25 thirty years ago. Today it costs $1.39. What is the percent increase?

I’m pretty sure the slope would be 1 since the x and y values increase by 1

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 *_*
