0, -1 I think. If that’s wrong use a calculator and take the answer and subtract it by the answer of the first problem
Solve for x then replace x with f⁻¹(x) and y with x
y=(4^x-5)/3
times 3
3y=(4^x-5)
add 5
3y+5=4^x
take log₄ both sides
log₄(3y+5)=x
switch
f⁻¹(x)=log₄(3y+5)
Step-by-step explanation:
4(5x-2) = 2(9x+3)
20x-8 = 18x+6
20x-18x = 6+8
2x=14
x= 14/2
∴ x= 7 [ANS]
