In the expression -5g12 whIn the expression -5g12 which part is the coefficient?ich part is the base?
1 answer:
Answer:
The coefficient is -5, and the base is 12.
Step-by-step explanation:
The coefficient is the number that the variable is being multiplied by in an expression, so -5 would be the coefficient in the expression . The base would be the little subscript number that is next to the variable, so the base in the expression
is 12.

How to find inverse function:
Step 1: Write down equation.
Remeber Ruler notation that
f(x)=y so we replace y with f(x).
Next, we must isolate x so first we subtract 3.
Divide both sides by 4.
Remeber that sin^-1x and sin x are inverse functions so they will cancel out to x. So we get
Swap x and y. So our inverse function is
If you want another proof: Here's one,
Let plug an a x value for the orginal equation,
4 sin x+3. Let say that
We then would get
So when x=pi/2, y=7.
By definition of a inverse function, if we let 7 be our input, we should get pi/2. as a output.
So let see.
So this is the inverse function of 4 sin x+3.
1b. The range of f(x) is [-1,7).
We can use transformations to describe range.
We have
Parent function is
with a range of [-1,1].
We then vertical stretch by 4 so we get
and our range will be
[-4,4].
Then we add a vertical shift of 3.
So our range of 4 sin x+3.
[-1,7].
1c. Domain of a inverse function is the range of the orginal function.
The range of f(x) is [-1,7) so the domain of f^-1(x) is [-1,7].
f(x) domain was restricted to -pi/2 to pi/2 so the range of f^-1(x) is [-pi/2, pi/2]
