Answer 2

1) Answer

Given,

$f(x) = 5x - 3$

●$\large\boxed{\textsf{\textbf{\pink{At x = 0\::-}}}}$

$f(x) \: is \: continous \: at \: x = 0 \:$

$\frac{lim}{x→0} = f(0)$

$L. H. S$

$\frac{lim}{x→0} f(x)$

$\frac{lim}{x→0}(5x - 3)$

$putting \: x = 0$

$= 5(0) - 3 \\ = - 3$

$R. H. S$

$f(0) \\ = 5(0) - 3 \\ = 0 - 3 \\ = - 3$

Since L.H.S = R.H.S

Hence,

$f \: is \: continuous \: at \: x = 0$

●$\large\boxed{\textsf{\textbf{\pink{At x = -3 \::-}}}}$

$f(x) \: is \: continuous \: at \: x = - 3$

$\frac{lim}{x→ - 3} f(x) = f( - 3)$

$L.H.S$

$\frac{lim}{x→ - 3} f(x)$

$= \frac{lim}{x→3} (5x - 3)$

$putting \: x = - 3$

$= 5( - 3) - 3$

$= - 18$

$R.H. S$

$f( - 3)$

$= 5( - 3) - 3 \\ = - 15 - 3 \\ = - 18$

Since L.H.S =. R.H.S

Hence,

$f \: is \: continuous \: at \: x = - 3$

●$\large\boxed{\textsf{\textbf{\pink{At x = 5 \::-}}}}$

$f(x) \: is \: continuous \: at \: x = 5$

$\frac{lim}{x→ 5} f(x) = f( 5)$

$L.H.S$

$\frac{lim}{x→ 5} (5x - 3)$

$putting \: x = 5$

$= 5(5) - 3$

$= 22$

$R.H.S$

$f(5) \\ = 5(5) - 3 \\ = 2 5- 3 \\ = 22$

Since L. H. S = R. H. s

Hence,

$f \: is \: continuous \: at \: x = 5$

thus,the function is continuous x =0,x = -3, x = 5
