Bonsoir,
h(x) = 5[tex]x^{2}[/tex]-3x+3
a. h(-3) = 5*[tex](-3)^{2}[/tex]-3*(-3)+3
=45+9+3
= 57
b. h([tex]\frac{2}{3}[/tex]) = 5*[tex](\frac{2}{3} )^{2}[/tex]-3*[tex]\frac{2}{3}[/tex]+3
= 5* [tex]\frac{4}{9}[/tex] - 2+3
=[tex]\frac{20}{9}[/tex] + 1
= [tex]\frac{29}{9}[/tex]
c. h(0) = 5*[tex]0^{2}[/tex]-3*0+3
= 5*0-3*0+3
=0-0+3
=3
