Answer:
f(x) + g(x) = x^2 + 4x + 35
Step-by-step explanation:
Add like terms from f(x) and g(x):
f(x) + g(x) = x^2 + 3x + 28 + x + 7, or
f(x) + g(x) = x^2 + 4x + 35
First it is reflected in the x axis (beacuse the x value becomes negative but the y values stays the same) second its dilated by a factor of a half ( the sides of the figure are reduced by a half) then its translated 2 units to the left and 2 units upwards
0
evaluate g(7) by substituting x = 7 into g(x
g(7) = (49-35-10)/2 = 4/2 = 2
now substitute x = 2 into f(x)
f(2) = √(4 - 48 + 144) = √0 = 0
(f ○ g)(7) = 0
