Answer:
<h2> f(-7) = 249 </h2>Step-by-step explanation:
To find f(-7) , substitute the value of x that's - 7 into f(x). That is for every x in f(x) replace it with - 7
We have
We have the final answer as
<h3>f( -7) = 249</h3>Hope this helps you

We will use trigonometric identities to solve this. I will use θ (theta) for the angle.
First of all, we know that cotθ = 1/tanθ. This is a trigonometric identity.
We can replace cotθ in the expression with 1/tanθ.
Simplify: 1/tanθ * tanθ = tanθ/tanθ = 1
So now, we have:
Next, we also know that secθ = 1/cosθ. This is another trigonometric identity.
We can replace secθ with 1/cosθ in our expression.
Simplify:
Our third trigonometric identity that we will use is tanθ = sinθ/cosθ.
We can replace sinθ/cosθ with tanθ.
Now we have as our final answer:
Hope this helps!
