Which function is quadratic?
1 answer:
Answer:
g(x) is a quadratic function ⇒ 2
Step-by-step explanation:
- The quadratic function is the function that has 2 as the greatest power of the variable
- The form of the quadratic function is f(x) = ax² + bx + c, where a, b, and c are constant
Let us use the information above to solve the question
∵ f(x) =
∵ x is the exponent of the base 1.5
→ That means f(x) is not in the form of the quadratic function
∴ f(x) is not in the form of the quadratic function above
∴ f(x) does not represent a quadratic function
∴ f(x) is not a quadratic function
∵ g(x) = 500x² + 345x
∴ The greatest power of x is 2
→ That means g(x) is in the form of the quadratic function above
∵ g(x) is in the form of the quadratic function above, where a = 500,
b = 345, and c = 0 (constant values)
∴ g(x) represents a quadratic function
∴ g(x) is a quadratic function

Answer:
$11535.60
Step-by-step explanation:
We have been given that Jackson deposited $5000 at 3.8% interest compound continuously when he was 18 years old.
To find the amount that Jackson will earn when he is 40 years old, we will use compound interest formula.
A= Amount after T years.
P= Principal amount.
e= Mathematical constant e.
r= Interest rate (in decimal form).
T= Time in years.
Let us convert our given interest rate into decimal form.
Upon substituting our given values in above formula we will get,
Therefore, Jackson will have $11535.60 in his account when he is 40 years old.
