Write an equation for the quadratic function that has

Mathematics
1 answer:
Degger [83]3 years ago
7 0

The quadratic function has an x-intercept of (-7,0)

and passes through (-4,-18)

The gradient(m) of its graph is (-18 - 0) ÷ (-4 - -7) = -18/3 = -6

Taking a point (x,y) the equation is;

(y - 0) ÷ (x - -7) = -6

y = -6x - 42

In the xy-plane, the graph of function f(x) has zeros at −5, −2, and 2. Write the polynomial function.
Alona [7]

Answer:

f(x) = x^3 +5x^2-4x-20

Step-by-step explanation:

Given

Zeros: -5,-2,2

Required

The polynomial function

If a function has a, b and c as its zeros, the function is:

f(x) = (x - a)(x - b)(x - c)

So, we have:

Zeros: -5,-2,2

f(x) = (x - (-5))(x - (-2))(x - 2)

Open the inner brackets

f(x) = (x +5)(x +2)(x - 2)

Expand the difference of two squares

f(x) = (x +5)(x^2 - 4)

Expand

f(x) = x^3 +5x^2-4x-20
