Answer:

Yes, the given relation is a function.

Step-by-step explanation:

Given the quadratic function, y = (x + 1)², and the domain of {-2, -1, 0, 1, 2, 3}:

By definition, a function is a relation in which no two ordered pairs have the same first component (x-values) and different second components (y-values). Observing the given domain, there are no repeating input values.

Therefore, the correct answer is that the relation is a function.

Nesterboy [21]

Answer:

$425\geq x$

425 pounds or less can be added after the student and football player.

Step-by-step explanation:

let x = remaining weight

(note that >/= is greater than or equal to.)

800 - 280 - 95 >/= x

425 >/= x

Find the gradient of the line 2y - 8x = -2

natima [27]

answer:

gradient is 4

Step-by-step explanation:

gradient is another way of saying slope

slope in the math is often used to show the speed of something

it's the m in y= mx+b

make the equation look like

y = mx + b

2y - 8x = -2

2y = 8x - 2

y= (8x-2)/2

y=4x-1

gradient is the number next to x

answer : gradient is 4

A model rocket is launched with an initial upward velocity of 60 m/s. The rocket's height h (in meters) after t seconds is given

Vedmedyk [2.9K]

Answer:

0.47 and 11.53

Step-by-step explanation:

h = 60t − 5t²

27 = 60t − 5t²

5t² − 60t + 27 = 0

Quadratic formula:

x = [ -b ± √(b² − 4ac) ] / 2a

t = [ -(-60) ± √((-60)² − 4(5)(27)) ] / 2(5)

t = (60 ± √3060) / 10

t = 0.47 or 11.53
