Answer:
( 0 , 8)
Step-by-step explanation:
The y-intercept is when the graph intersects the y axis, in other words, when x is zero. Hence substitute 0 in for x
f ( x ) = 8 
f ( 0 ) = 8 
Any number to the power zero is one;
f ( 0 ) = 8 * 1
f(0) = 8
The y-intercept is 8.

Answer:
x = -3, 4/5
Step-by-step explanation:
To factor the equation, you need to find factors of (5)(-12) that have a sum of (+9).
(5)(-12) = -60 = 60(-1) = 30(-2) = 15(-4) = 12(-5) = 10(-6)
The factors 15 and -4 have a sum of 9, so we can factor the equation as ...
5x² +15x -4x -12 = 0
5x(x +3) -4(x +3) = 0 . . . . factor pairs of terms
(5x -4)(x +3) = 0
The solutions are the values of x that make these factors zero:
5x -4 = 0 ⇒ x = 4/5
x +3 = 0 ⇒ x = -3
The solutions are x = -3 or 4/5.
Answer:
x = √K - 2xh - h²/a
Step-by-step explanation:
a(x+h)²=k
a * x² + 2xh + h² = k
a * x² = K - 2xh - h²
x² = K - 2xh - h²/a
x = √K - 2xh - h²/a
