<h3>
Answer: C) Discriminant</h3>
The formula for the discriminant is
d = b^2 - 4ac
If d < 0, then there are no real number solutions
If d = 0, then you have exactly one real solution
If d > 0, then you have two different real number solutions
Hope this helps! f-1(x)=x/2-1/2
Answer:
Slope formula: (b) m = y2 – y1 / x2 – x1
Point-Slope Formula: (c) y – y1 = m (x – x1)
Slope Intercept Form: (a) y = mx + b
