Question

Medal for anyone who can help!!!!
how many real-number solutions does the equation y= -4x^2+7x-8 have?

Answer 1

A. no solutions
B. one solution
C. two solutions
D. infinitely many solutions

Answer 2

either solve it using the quadratic formula, or check the discriminant
\[b^2-4ac\]
answer D makes no sense

Answer 3

ooh maybe i misinterpreted the question

Answer 4

\[y= -4x^2+7x-8 \] has infinite number of solutions
pick an \(x\) you will find a \(y\)
\[ -4x^2+7x-8=0\] maybe what is meant by "solutions"
