Replace all the x values with -3
f(-3)=-2(-3)^2+5(-3)
f(-3)=2(9)-15
f(-3)=18-15
f(-3)=3
Hope I helped :)

plug -3 in for x. the equation should look like this
f(-3)=-2(-3)^2+5(-3)
simplify by multiplying and you get
f(-3)=6^2-15
now apply the exponent
f(-3)=36-15
finish it off by subtracting and you get
f(-3)=21
