Question

the value of f(x)=5x-4x+3 when x=-1, is: (1)3 (2)-12 (3)-6 (4)6​

Answer 1

Step-by-step explanation:

f(x)=5x-4x+3

when x= -1

f(-1) = 5(-1) - 4(-1) + 3

f(-1) = -5 + 4 + 3

f(-1) = 2

Answer 2

Answer:

2

Step-by-step explanation:

f(x) = 5x - 4x + 3

put x= -1

f(-1) = 5(-1) - 4(-1) + 3

f(-1) = -5 + 4 + 3

f(-1) = -1+3

f(-1) = 2
