Question

Which of the following best describes the graph of f(x) = x2 + 3x - 10?

Minimum at (1.5, -12.25) with intercepts at (5, 0) and (-2, 0)

Minimum at (-1.5, -12.25) with intercepts at (-5, 0) and (2, 0)

Minimum at (-3.5, -2.25) with intercepts at (-5, 0) and (-2, 0)


Minimum at (3.5, -2.25) with intercepts at (5, 0) and (2, 0)

Answer 1

@Legends do you understand this

Answer 2

sadly no

Answer 3

Sorry @TTP wish i could help

Answer 4

Solve the quadratic (it factors) and obtain the 2 y intercepts

Answer 5

There is only one choice that matches the intercept, so you won't need to determine minimum, but if you did it just for kicks, differentiate the equation and set the derivative to 0 and solve for x.
