Question

Graph the function and then use the graph to find the indicated limit.

f(x) = 5x-3, lim x-->5 F(x)

Answer 1

we have no graph provided but
for x approaches 5
do f(5)
f(5)=5(5)-3
f(5)=25-3
f(5)=22

the limit of f(x) as x approaches 5 is 22

Answer 2

if f(x)=5x-3 the function is continuous for all real values of x so we can simply find f(5)=5(5)-3

f(5)=22
