Answer:
2
Step-by-step explanation:
y = 0 at the point where the function intersects x-axis. Thus, yiou have to put
2x2 + x - 10 = 0
and solve the equation. It is better to factor the quadratic expression, which gives us
2x2 + x - 10 = (2x+5)(x-2) = 0
We have 2x +5 = 0 and x-2 = 0. Thus, the intercepts are x = -5/2 = - 2.5 and x = 2.
