Answer:
y=x^2+7x+4
Step-by-step explanation:
because the sign before x^2 is positive, the graph would concave up, if there's only one intercept, it has to be the vertex. the vertex is the critical point.
solve every make the derivative of each function equals zero, you get the x where the vertex shall be, then get this"x" into y=x-5 see if the y in y=x-5 is equal to y=x^2+6x+9 or other options.
let me give u an example.
for y=x^2+x-4, the critical point shall be 2x+1=0,x=-1/2, and the y is -4.25,
if you plug x=-1/2 into y=x-5, it's -5.5, -5.5 doesn't equal to -4.25
Answer:
I think theres something wrong with the question but I got 30
Step-by-step explanation:
y= (-x) +2
when x =32
y= (-32)+2
y= -32+2
y=30
Answer:
Your answer would be 
.
Step-by-step explanation:
The formula for the equation of a circle is 
, where (h, k) is the center of the circle, and r is the radius. Since the center is (-1, 3), the left half of the equation is 
. Now, all we have to do now is find the radius, r. To do that, you can use the distance formula to find the distance between the center (-1, 3) and a point that passes through the circle, or is on the circumference, (-4, -2). When you calculate that, you will get 
, so the radius is 
. But, we want the radius squared, which is 34. So, the final answer is what I wrote above.
Hope that helped! :)
