You need to find where the discriminant is less than zero
Remember the discriminant is b^2 - 4ac
a = m
b = -5
c = -2
Set up the inequality like this
(-5)^2 - 4m(-2) < 0
25 + 8m < 0
8m < -25
m < -25/8 < -3.125
So any number less than -3.125 will make this graph have no x-intercepts (or real roots)
C is the independent variable because it is all by itself.
It is irrational. Meaning not rational because decimals cannot be fractions.
The answer is A) 36.43, 36.29, 34.8
Have a great day!~
