Answer:
The value of f(-3) is 21
Step-by-step explanation:
[tex]f(x)= 2x^2-x[/tex]
we need to find out f(-3) using the given f(x)
f(-3) means x is -3, plug in -3 for x
[tex]f(x)= 2x^2-x[/tex]
[tex]f(-3)= 2(-3)^2-(-3)[/tex]
[tex]f(-3)= 2(9)-(-3)[/tex]
[tex]f(-3)= 18+3= 21[/tex]
The value of f(-3) is 21
