Question

The below quadratic function can model the natural shape of a banana. Now, we know that a

parabolic shape must have a quadratic function, therefore an equation in standard form of

f(x)=ax2 + bx + c. To find an equation for the parabolic shape of the banana, we need to find

the values of a, b, and c. From the banana picture above, we can see that a quadratic function

is able to model the banana quite accurately, with a=0.1, b=0, and c=0. Therefore, the equation

is f(x)=0.1x2

.

(i) Name the shape of the banana curve from the above figure.

(ii) Find the number of the zeroes of the polynomial for the shape of the banana.

(iii)If the curve of banana represented by f(x) = x2

– x – 12. Find its zeroes.

(iv)If the representation of banana curves whose one zero is 4 and the sum of the zeroes is 0

then find the quadratic polynomia​

Answer 1

Answer:

x=19 ans of the sum...........

Answer 2

or

I . semicircle

ii . no. of zeroes = 1

iii. x = 4 and x = -3

therefore , alpha = 4 , and Beta = -3

Thankyou....
