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
<span>To determine the value of c, we can use cross multiplication of the given ratios composing the proportion. 13 times 3 is equal to 39. Then, divide the obtained answer by 6 giving us the final answer which is equal to 6.5.
Hence, the answer to this item is 6.5</span>

Answer: y = (1/3)x - 2</h3>
Explanation:
The y intercept is -2 because the line crosses the y axis at this location. So b = -2
The slope is m = 1/3 because we go up 1 and over to the right 3 units. For instance, going from (0,-2) to (3,-1) follows this pattern.
You can use the slope formula for two points like (x1,y1) = (0,-2) and (x2,y2) = (3,-1) to find that m = 1/3
The slope formula is m = (y2-y1)/(x2-x1)
So that's how we go from y = mx+b to y = (1/3)x-2
(4-fx)/3 or (fx-4)/3 i think
