Answer:
<em>a^2 +3a-2</em>
Step-by-step explanation:
Given the expression:
g(x) = x^2 +3x-2
We are to find f(a). To get this, we will simply replace x with a in the expression as shown;
g(a) = a^2 +3a-2
<em>hence the required domain is expressed as g(a) = a^2 +3a-2</em>
For this, I got the equation (X+3)^2-2 or X^2+6X+7. I used this method:
First I set up an equation (X+H)^2-K, where (K, H) is the vertex. All we have to do is find where the graph reaches its minimum value (because it opens upwards), then find the x-coordinate that lies there, which is (-2,3). Substituting these value in for H and K, we get the equation <span>(X+3)^2-2 or simplified X^2+6X+7.

0.004 is much less than 4.00!
If the family walked 2/5 of a mile in 2/7 of an hour their MPH would be 2.8mph
I might be wrong but it should be 1
