Question

For f(x)=-4x+2, find f(-1)

Answer 1

F(x) and F(-1)
Do you see the notation and how it relates?

Answer 2

\[f(\spadesuit)=-4\times \spadesuit+3\]
\[f(-1)=4\times (-1)+2\]

Answer 3

Give satellite a medal if you haven't already done so @Kasie

Answer 4

f(♠)=−4×♠+3
f(−1)=4×(−1)+2 = -2

Answer 5

That's not showing all of the steps, you just showed what satellite put and then put the answer there... That's like going:

x^2 + 4x - 2 = -2 -sqrt -6

Answer 6

Thanks @satellite73
