What the rate of change for f(t)=70(5/2)^t
help

Which equation represents a proportional relationship that has a constant of proportionality equal to 1/5

Which value is not a solution of 8x^3 – 1 = 0

Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. 3, 4+2i, 1+(sqrt)7 the answer is supposed to be: f(x)=x(^5)-13x(^4)+60x(^3)-82x(^2)- 144x+360 what am i doing wrong?
