Answer: 22
Step-by-step explanation:
Evaluate g + 3h - 6 when g = 10 and h = 6.
Substitute the values of g and h into the expression :
10 + 3(6) -6.......open the bracket
= 10 + 18 - 6
=28 - 6
= 22

Answer:
No
Step-by-step explanation:
Substitute any number for x
6(3)-3+5
6(3)= 18
18-3= 15
15+5= 20
6+5=11
20≠11
Answer:
To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and f^-1(x)= ln(x+4)/2
Step-by-step explanation:
f(x) = e^2x - 4
to find the inverse let
y = e^2x - 4
Replace x and y
x = e^2y - 4
and now, solve to find value of y
x + 4 = e^2y
taking ln on both sides:
ln(x+4) = ln(e^2y)
ln(x+4) = 2y
=> y = ln(x+4)/2
=> f^-1(x)= ln(x+4)/2
So, To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and f^-1(x)= ln(x+4)/2
