J(x) = 3x² + 2x – 5 Find J(3)

Mathematics
1 answer:
SpyIntel [72]1 year ago
4 0

Answer:

28

Step-by-step explanation:

J(x) = 3x^2 + 2x - 5

they have asked us to find J(3), therefore substitute x with 3 throughout the equation.

j(3) = 3*3^2 + 2*3 - 5

J(3) = 3*9 + 6 - 5

J(3) = 27 + 6 - 5
J(3) = 33 - 5 = 28

Y=-2|x+2|-4 i need to find y intercept and the x intercept
NeTakaya

Answer:

x-int: ∅

y-int: (0,-8)

Step-by-step explanation:

To find the x and y-intercept, simply plug in zero for x and y:

0=-2|x+2|-4\\4=-2|x+2|\\-2=|x+2|\\

Because an absolute value cannot be equal to a negative, there is no x-intercept.

y=-2|0+2|-4\\y=-2|2|-4\\y=-4-4\\y=-8

Hope it helps :)
