Answer:
Step-by-step explanation:
[tex] {x}^{2} - 3x + 8[/tex]
(Putting value of x = 4)
[tex] = {4}^{2} - 3 \times 4 + 8[/tex]
= 16 - 12 + 8
= 24 - 12
= 12 (Ans)
Answer:
It is 12
Step-by-step explanation:
[tex]f(x) = {x}^{2} - 3x + 8[/tex]
When x is 4, substitute x as 4:
[tex]f(4) = {(4)}^{2} - 3(4) + 8 \\f(4) = 16 - 12 + 8 \\ f(4)= 12[/tex]
