Question

Select the approximate values of x that are solutions to f(x) = 0, where
f(x) = -5x2 + 7x + 4.


a.{–0.44, 1.84}

b.{-5, 7}

c.{–1.40, –0.80}

d.{–1.25, 1.75}

For some reason, I am thinking it is -5,7

Answer 1

Oops it's actually -5x^2

Answer 2

Looks like (a) to me.

Just use the quadratic formula.
