Complementary angles add up to 90 degrees.
So we can write:
42 + x = 90
To solve, subtract 42 to both sides:
x = 48
So the complement of a 42 degree angle is a 48 degree angle.
An exponential decay function goes down to the right, like in the picture attached.
An exponential function follows this format: 
, where b is less than 1 and more than 0. b is more than 0 but less than 1 in function A.

Answer:
Step-by-step explanation:
f(2) = -2^2 + 2 + 14 = -4 + 2 + 14 = 12
Let x is the smaller integer.
x+12 is the larger integer because two integers differ by 12.
The sum of their square means
x² + (x+12)² = 74
x² + x² + 24x + 144 = 74
2x² + 24x + 70 = 0
2(x² + 12x + 35) = 0
2(x+5)(x+7) = 0
x = -5 or - 7
so we have two answer.
first x = -5 as smaller and 7 as the larger x = -5 + 12 = 7
second x = -7 as smaller and 5 as the larger. x = -7 + 12 = 5
