Question

Calcule o valor de h(x) = 4x² - 6x + 3,para :

A )x= -2 B) x= 0 C) x = 3

Answer 1

a) 4(-2)² - 6(-2)+3==== 4.4+12+3= 16+12+3=31
b)4(o)²-6(0)+3=3
c 4(3)²-6(3)+3=== 4.9-18+3=36-18+3=21

Answer 2

h(x) = 4x² - 6x + 3

A)x=-2
h(-2) = 4(-2)² - 6(-2) + 3
h(-2)=4(4)-(-12)+3
h(-2)=16+12+3
h(-2)=31
 
B) x= 0
h(0) = 4(0)² - 6(0) + 3
h(0)=4(0)-(0)+3
h(0)=0-0+3
h(0)=3
 
C) x = 3
h(3) = 4(3)² - 6(3) + 3
h(3)=4(9)-(18)+3
h(3)=36-18+3
h(3)=21
