Answer:
D
Step-by-step explanation:
We need to find 2 roots of the quadratic function given and find the greater of the two roots.
We factorize the quadratic and find the two solutions first:
![x^2-6x+5=0\\(x-5)(x-1)=0\\x=1,5](https://tex.z-dn.net/?f=x%5E2-6x%2B5%3D0%5C%5C%28x-5%29%28x-1%29%3D0%5C%5Cx%3D1%2C5)
So,
x = 1
and
x= 5
Out of the two, x = 5 is the greater root.
D is the correct answer.
Answer:
$10
Step-by-step explanation:
Given the supply function between the price and quantity of baskets from Ben's farm stand is defined by;
P = Q - 15
where P is the price and Q is the quantity of baskets. If Ben makes 25 baskets
then Q = 25
P = 25 - 15
P = $10
He will sell the baskets of peaches at $10.
Answer:
The range of the function is {-1 , -11 , 7}
Step-by-step explanation:
- The range is the resulting values of y we get after substituting all
the possible values of x
- The domain of the function is the values of x
- The range of the function is the values of y corresponding to the
values of x ⇒ [y = f(x)]
∵ f(x) = -2x² + 7
∵ The domain D = {2 , -3 , 0}
- We need to find the values of f(x) corresponding to x = 2 , x = -3
and x = 0
- Substitute the values of x in f(x)
∵ x = 2
∴ f(2) = - 2(2)² + 7
∴ f(2) = -2(4) + 7
∴ f(2) = -8 + 7
∴ f(2) = -1
∵ x = -3
∴ f(-3) = - 2(-3)² + 7
∴ f(-3) = -2(9) + 7
∴ f(-3) = -18 + 7
∴ f(-3) = -11
∵ x = 0
∴ f(0) = - 2(0)² + 7
∴ f(0) = -2(0) + 7
∴ f(0) = 0 + 7
∴ f(0) = 7
The range of the function is {-1 , -11 , 7}
