The value of Discriminant is -28.

The discriminant is negative, it implies that the function has no real solution.

Step-by-step explanation:

Given,

f(x)=-4x^2+10x-8

We need to find the value of discriminant.

And also we need to find the number of real zeros 'f(x)' have.

Solution,

We have given the quadratic equation;

f(x)=-4x^2+10x-8

where

$a = -4\\\\b = 10\\\\c = -8$

Now we will find the Discriminant.

Discriminant can be calculated by using the formula b^2 - 4ac .

Substituting the values we get;

$D=b^2 - 4ac = 10^2-4\times(-4)\times(-8)=100-128 =-28$

Hence the value of Discriminant is -28.

Since the discriminant is negative, it implies that the function has no real solution.
