Convert the following quadratic function from vertex form to standard form. f(x)=-3(x-4)^2+7

1 answer:

4 0

The graph of the quadratic function in standard form, f(x) = ax² + bx + c, is a ... f(x)= (3x – 5)(7x – 13); y = (5x – 7)(6x – 5) ... Intercept form: y = 9(x - 2/3 + √3/3)(x - 2/3 - √3/3) = (3x – 2 + ... Find p and q to convert f(x) to the Vertex Form: f(x) = a*(x + p)² + q ... Solution. y = 5*(x² - 8x/5 + 2/5) = 5(x –4/5)² – 16/5 + 2.

What polynomial has roots of -5,-4 and 1

Semenov [28]

x³ + 8x² + 11x - 20 ← the first on list

given the roots of a polynomial, say x = a, x = b and x = c

then the factors are (x - a), (x - b) and (x - c)

the polynomial is the product of the factors

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

here x = - 5, x = - 4 and x = 1, hence factors are

(x + 5), (x + 4) and (x - 1)

f(x) =(x + 5)(x + 4)(x - 1) ← expanding factors gives

f(x) = (x² + 9x + 20)(x - 1) = x³ + 8x² + 11x - 20

kherson [118]

Answer:

Step-by-step explanation:

1.C. circumference

2.D. 25.12 decimeters

Solution

C=2πr=2·π·4≈25.13274

3.B. 28.26 meters

Using the formulas

C=2πr

d=2r

Solving for C

C=πd=π·9≈28.27433m

4.B. 25.12 meters

Using the formulas

C=2πr

d=2r

Solving for C

C=πd=π·8≈25.13274m

5.B. 21.98 meters

Using the formulas

C=2πr

d=2r

Solving for C

C=πd=π·7≈21.99115m
