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:
In interval notation:
Domain: [1, 9]
Range: [2, 7]
Step-by-step explanation:
The domain of a function is all off the possible input (x) values, and the range is all of the possible output values (y). All of the input and output values are already given in the table.
Concept
Quotient the number obtained by dividing one number by another Dividing 10 by 5 gives a quotient of 2.
Answer:
i think the answer is
225 beacuse 15×15=225=r^2
