Which function is a quadratic function?
p(x) = 2x(x2 + 6) + 1
m(x) = –4(x + 3) – 2
t(x) = –8x2(x2 – 6) + 1
h(x) = 3x(x – 2) – 4

h(x) = 3x(x – 2) – 4

Step-by-step explanation:

In a quadratic function, the greatest power of the variable is 2. To find out the greatest power, we need to write the function in a polynomial form.

p(x) = 2x(x^2 + 6) + 1 = 2x^3 + 12x + 1

The greatest power of x is 3, p(x) is not quadratic.

m(x) = -4(x+3) - 2 = -4x -12 - 2 = -4x - 14

The greatest power of x is 1, m(x) is not quadratic.

t(x) = –8x^2(x^2 – 6) + 1 = -8x^4 + 48x^2 + 1

The greatest power of x is 4, t(x) is not quadratic.

h(x) = 3x(x – 2) – 4 = 3x^2 - 6x - 4

The greatest power of x is 2, h(x) is quadratic.

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.

the answer to this is:

factor 2x2+16x+24

2x2+16x+24

=2(x+2)(x+6)

answer:

2(x+2)(x+6)
