Domain: all real numbers, since no number can make this function undefined
Range: since this an upward opening parabola(because the quadratic coefficient is positive), and the minimum point is 23, the range is going to be any number equal or greater than 23.
Finding the coordinates of the vertex is straightforward here, since we're given a good, clear diagram.
The vertex, in this case, is the lowest point of this graph. By counting from y-axis leftward, we see that the x-coordinate of the vertex is -4; by counting up to the y-axis, we see that the y-coordinate of the vertex is -4.
Thus, the vertex is located at (-4,-4).
If you are just supposed to evaluate the a) f(0) and b) f(4) then you would just plug it in the equation.
f(0)=0^2 - 8*0 + 16
f(0)=0 - 0 + 16
f(0)=16
f(4)=4^2 - 8*4 +16
f(4)=16 - 32 + 16
f(4)=0

Answer:
1
Step-by-step explanation:
Note there is a common ratio between consecutive terms, that is
10 ÷ 20 = 5 ÷ 10 = 2 ÷ 5 =
Thus to obtain the next term in the sequence multiply the previous term by
2 × = 1
