Answer:
h(4) = 3
f-1(-3) = - 1
Step-by-step explanation:
One
h(x) = 2x - 5
h(4) = 2*4 - 5
h(4) = 8 - 5
h(4) = 3
Two
Let y = f(x)
y = 5x + 2 Interchange x and y
x = 5y + 2 Subtract 2 from both sides
(x - 2) = 5y Divide by 5
(x - 2)/5 = y
but y = f'(x)
so f(x) = (x - 2)/5
f-1(-3) = (-3 - 2) / 5
f-1(-3) = -5/5
f-1(-3) = - 1

Answer:
5 + 5 = 10
Step-by-step explanation:
If you know that 5 + 5 = 10, you can solve 5 + 6 = 11. You are adding one more to the addends (adding 6 instead of adding 5), so you add one more to the sum (11 instead of 10).
