Answer:
300
Step-by-step explanation:
Answer: a) 
Step-by-step explanation:
Since we have given that

a.) Find the inverse of f(x) and name it g(x).
Let f(x) = y
So, it becomes
Switching x to y , we get


b) . Use composition to show that f(x) and g(x) are inverses of each other.

Similarly,

so, both are inverses of each other.
c) Draw the graphs of f(x) and g(x) on the same coordinate plane.
As shown below in the graph , Since for inverse function we need an axis of symmetry i.e. y=x
And both f(x) and g(x) are symmetry to y=x.
∴ f(x) and g(x) are inverses of each other.
Answer:
C) -3
Step-by-step explanation:
Rearrange your equation so that it is in slope-intercept form (y = mx + b). The m in the equation is the gradient.
y = 7 - 3x
y = -3x + 7
The m-value is -3. This means that the gradient is -3.
