Question
The y-intercept of the function f(x) = x2+3x+2
Answer:
4 + 3x
Y=(5x-4)/2 first move -2y to the other side to obtain a positive value and make y the subject
ANSWER
The radius is 4
EXPLANATION
The given equation is:

We complete the square to get the expression in standard form:


We factor using perfect squares to get:

This implies that,

Comparing to

The radius is r=4
3.14*d
3.14*12= 37.68
Rounded to the nearest hundredth would be 37.7
Any fraction that does not equal 1/2.
