Question

[
begin{array}{c}
frac{operatorname{din} 9}{4} frac{1}{4^{x}-1}
4^{x}-1=0
y^{x}=1
end{array}
]
Take wo g
[
x log 4=log 1 quadleft[log 2^{a}=a log 2right]
]
[
begin{array}{l}
2 x log 2=log 1 quad[log 1=0]
2 x=0
frac{x=0}{frac{x}{2}}
end{array}
]
Jowt it is given for ( x=0 )
Valure of ( f(x)=0 )
Hen wi functuon is conturums at
cremy pornt

# The function f(x) = { 4* - 1 is continuous x= 0 (a) everywhere except at x = 0 and x=1 (b) nowhere (c) everywhere (d) everywhere except at x = 0

Solution
