Given: [tex]f(x)=2x^{2} -3x[/tex]

Find:

[tex]f(-3)[/tex]

Solution:

[tex]{\tt{f(x)=2x^{2} -3x}}\\{\tt{f(-3)=2(-3)^{2}-3(-3)}}\\{\tt{f(-3)=2(9)+9}}\\{\tt{f(-3)=18+9}}\\{\boxed{\tt{f(-3)=27}}}[/tex]

Answer:

[tex]{\purple{\boxed{\purple{\huge{\boxed{\sf{f(-3)=27}}}}}}}[/tex]

[tex]{\blue{\boxed{ItzyMidzy:))}}}[/tex]
