Answer:
This tells us that the vertex is at (−2, 9) and the equation of the axis of symmetry is x = −2. To find the x-intercepts, we put y = 0 to obtain
(x + 2)2 − 9 = 0
(x + 2)2 = 9
x + 2 = 3 or x + 2 = −3
x = 1 or x = −5.
Step-by-step explanation:
Image result for Which quadratic function has a y-intercept of 4? y=x2−2x+4 y=x2+2x+9 y=−x2+3x y=x2+13x+12
The standard form of a quadratic equation is written as y=ax2+bx+c, where x and y are variables and a, b, and c are known constants. To find the y-intercept from a quadratic equation, substitute 0 as the value for x and solve. The y-intercept is always equal to the value of c in the equation.
Answer:
In 9 years, you will have $5,499.18
Steps:
Note
A = Final Amount
P = Principal Amount
R = Interest Rate
N = # of times interest is compounded
T = Time in years
A = P(1 + r/n)^nt
A = ?
P = 4000
R = 0.036
N = 1
T = 9
A = 4000(1 + 0.036/1)^1*9
A = 5499.18
