ok, one of the "easier" ones...
what is the range of the function, f(x )= 2x² - 7x + 1 , -2 ≤ x ≤ 3
thanks in advance to anyone who can help
remember, the range is the set of y-values for which your function is defined, given some domain. on an unrestricted domain, a parabola where the coefficient is positive has range $\displaystyle [ \text{vertex}, \infty)$. so start there, but note that you can't go all the way up to $\displaystyle \infty$ here, since your domain is restricted
