Discriminant value:

In quadratic function f(x)=ax^2+bx+c Where  a,b are coefficients, x  is the variable and c is the constant term.

If discriminant value b^2-4ac then the graph f(x)=ax^2+bx+c has one x-intercept and touches the x-axis at its vertex.

b^2-4ac is called the discriminant value of the polynomial in the quadratic function. The discriminant term gives solutions to the function.

Given:  a=1;b=5;c=4

Apply these values in the expression,

b^2-4ac=(5)^2-4(1)(4)\\b^2-4ac=25-16\\b^2-4ac=9

Therefore, the value  b^2-4ac is 9
