Answer: 15/2,11/2
Step-by-step explanation:
From the given options we can think that x is
in the exponent of 3.
So, the given function is actually f(x) = 3^x +9
Now, we need to find the range of given
function.
We can see that first term is and exponential
term 3^x and second term is 9
We know that 3^x will always be greater than
O.
Therefore, 3^x +9 would always be greater
than 9.
Therefore, range would be y>9.
So, the correct option is B) (y | y > 9}.
The coordinates of the midpoint of the line segment is the average of the coordinates of both end points. For this example above, let (x, y) be the coordinates of point Q.
(abscissa) -6 = (-1 + x) / 2 ; x = -11
(ordinate) -3 = (-4 + y) / 2 ; y = -2
Therefore, the coordinates of point Q is (-11, -2). The answer is letter A.
