Answer:

No, the function has no real number zeros

Step-by-step explanation:

we know that


The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to


[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]


in this problem we have


[tex]f(x)=2x^{2} -3x+3[/tex]  

equate the function to zero

so


[tex]2x^{2}-3x+3=0[/tex]  

[tex]a=2\\b=-3\\c=3[/tex]


substitute in the formula


[tex]x=\frac{3(+/-)\sqrt{(-3)^{2}-4(2)(3)}} {2(2)}[/tex]


[tex]x=\frac{3(+/-)\sqrt{9-24}} {4}[/tex]


[tex]x=\frac{3(+/-)\sqrt{-15}} {4}[/tex]


remember that

[tex]i=\sqrt{-1}[/tex]

[tex]x=\frac{3+\sqrt{15}i} {4}[/tex]


[tex]x=\frac{3-\sqrt{15}i} {4}[/tex]


The function has no real number zeros

Since the discriminant is less than 0, hence the function has no real number zeros.

Discriminant of a function

The discriminant is used to determine the nature of a function. It is expressed as:

D = b^2 - 4ac

Given the quadratic function f(x) = 2x^2 – 3x + 3

a = 2

b = -3
c = 3

Substitute into the expression to have:

D = (-3)^2 - 4(2)(3)
D = 9 - 24
D = -15

Since the discriminant is less than 0, hence the function has no real number zeros.
