Answer:

  • 14

Step-by-step explanation:

Substitute x with -2 to find the value:

  • f(-2) = (-2)² - 3(-2) + 4 = 4 + 6 + 4 = 14

f(x)=x^2-3x+4

[tex]\\ \sf\longmapsto f(-2)[/tex]

[tex]\\ \sf\longmapsto (-2)^2-3(-2)+4[/tex]

[tex]\\ \sf\longmapsto 4+6+4[/tex]

[tex]\\ \sf\longmapsto 10+4[/tex]

[tex]\\ \sf\longmapsto 14[/tex]
