Question

Помогите пожалуйста срочно

Answer 1

F(3) = 21 * 3 - 7 = 63 - 7 = 56

f(0) = 21 * 0 - 7 = 0 - 7 = - 7

f(- 2) = 21 * (- 2) - 7 = - 42 - 7 = - 49.

g(x)=x^2-10x

g(8)=8^2-10*8=64-80= - 16

g (-3) = (-3) ² - 10 * (-3) = 9 + 30 = 39

g(0)=0^2-10*0=0-0=0

f(x)=x-6/x+4,x=/-4

f(-3)= - 3-6/-3+4= - 9/1= - 9

f(6)=6-6/6+4=0/10=0

f(0)=0-6/0+4= - 6/4= - 1,5
