F(x) = x + 5
x = f(x) - 5
Range = {7, 9}, then range = {7 - 5, 9 - 5} = {2, 4}
Answer:
if you are solving for X
Step-by-step explanation:
first you do a thing i call jump multiplying
so like 5x2X+ 5x4
then you do basic maths
10X=20
X=2
It is easiest to simply just substitute any of the choices into the original equation and see which one satisfies the equation.
Given the equation: 3 * |5 + x| = 12
Using choice A. x = 7
3 <span>* |5 + 7| = 12
</span>36 =/= 12
Using choice B. x = 1
3 <span>* |5 + 1| = 12
</span>18 =/= 12
Using choice C. x = -9
3 <span>* |5 + -9| = 12
</span>12 = 12
Therefore, the correct answer is C. -9
Answer:
5
Step-by-step explanation:
(5,3) are the coordinates, so x=5
Answer:
Step-by-step explanation:
The given equation of a parabola is,
When we compare this equation with the vertex form of the quadratic equation,
y = a(x - h)² + k
where (h, k) is the vertex,
Vertex of the parabola,
(-3, 4)
y-intercept,
x-intercepts,
(x + 3) = ±√8
x = (3 - 2√2), (3 + 2√2)
Axis of symmetry,
x = -3
Domain:
(-∞, ∞)
Range:
(-∞, 4]
