Answer:

Step-by-step explanation:
Given the expression:

We are to find the quotient as shown:

Hence the correct answer is 
I think you’re answer is option 1: 3x^2+5.
Explanation:
Evaluate f(x^2+2) by substituting in the value of g into f.
f(x^2+2)=3(x^2+2)-1
Then apply distributive property.
f(x^2+2)=3x^2+3•2-1
Then multiply 3 by 2.
f(x^2+2)=3x^2+6-1
Then subtract 1 from 6.
f(x^2+2)=3x^2+5

if 1 = 10 then 5 = 50 using the tens rule
<span>f(x)=<span>x2</span>−1</span>That means to find the value of the function at any value of x, we square x and subtract 1. If <span>x=2a</span>, we square <span>2a</span> and subtract 1:<span>f(2a)=(2a<span>)2</span>−1=4<span>a2</span>−1</span>Now, we know that <span>f(2a)=35</span>so we can find the value of a:<span>f(2a)=(2a<span>)2</span>−1=4<span>a2</span>−1=35</span><span>4<span>a2</span>−1+1=35+1</span><span>4<span>a2</span>=36</span><span><span>a2</span>=9</span><span><span>a=±3</span></span>
