Question

Y=f(x) где f(x)=9x+2

Answer 1

)y=f(x)
f(0)=9*0+2=2
f(-2)=9(-2)+2=-16
f(a-1)=9(a-1)+2=9a-9+2=9a-7

Answer 2

The equation $Y = f(x)$ is defined with the function $f(x) = 9x + 2$. This means that for any given value of $x$, you can find the corresponding value of $Y$ by substituting $x$ into the expression $9x + 2$.

For example, if $x = 1$, then $Y = f(1) = 9 \times 1 + 2 = 9 + 2 = 11$. Similarly, if $x = -2$, then $Y = f(-2) = 9 \times (-2) + 2 = -18 + 2 = -16$.

In general, this function represents a linear relationship between $x$ and $Y$, where the slope of the line is $9$ and the y-intercept is $2$.
