Answer:
241
Two zeros.
Step-by-step explanation:
In the general form ax² + bx + c = 0, the discriminant D is given by:
D = b²-4ac
If D<0, there are no real solutions
If D=0, there is one solution
If D>0, there are two solutions
For f(x) = 4x²-17x+3
D is calculated as 17^2 - 4×4×3 = 241
Since 241 is larger than zero, there are two solutions.
