Answer:
D
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x + 9 ← is in slope- intercept form
with y- intercept c = 9
then the line crosses the y- axis at (0, 9 )
Given the function . The above function can be written as
a)Now, the function has minimum value since the coefficient of
is
.
b) The minimum value of the function occurs at and its value is
c)The minimum value of the function occurs at .
