Which function is a quadratic function? t(x) = (x – 4)2 + 3 q(x) = (2x + 4)3 + 3 r(x) = (–6x – 4)4 + 3(x + 2)2 s(x) = –(x – 6) + 3(x + 1)

t(x) = (x – 4)^2 + 3

Step-by-step explanation:

Quadratic function is in the form of f(x)=ax^2 +bx+c  or f(x) = a(x-h)^2 + k which has highest exponent 2

t(x) = (x – 4)^2 + 3. It has highest exponent 2 so it is quadratic

q(x) = (2x + 4)^3 + 3 . It has highest exponent 3 so it is not quadratic

r(x) = (–6x – 4)^4 + 3(x + 2)^2 . It has largest exponent 4 so it is not quadratic

s(x) = –(x – 6) + 3(x + 1). It has largest exponent 1 so it is not quadratic

answer:

3 bags of apples and 2 bags of oranges.

step-by-step explanation:

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
