Question

if f(x)= 3x-1 then find f(0)+2f(-1)
please tell me the answer quick
please ​

Answer 1

answer is -9

Step-by-step explanation:

put x =0 ,in function f(x) to find f(0)

f(0)= 3*0 -1

f(0)= -1

then put x= -1 in function f(x) to find f(-1)

f(-1)=3*(-1) -1

f(-1)= -3-1 = -4

now ,

f(0)+2*f(-1)

-1 + 2*(-4)

-1-8= -9

so, -9 is the answer

Answer 2

Answer:

your answer:

Step-by-step explanation:

put x=0

= f (0+2) = 2f (0) - f ( 0+1 )

= f(2) - 2f(0) - f1

=f (2) = 2(2)-3

=f(2)=1
