Question

A quadratic function was translated 3 up. Give the equation and graph

Answer 1

i have the equation (x-1)^2+k is it right?

Answer 2

@loveboy

Answer 3

Why (x-1)^2 ?

Answer 4

the equation for quadric is (x-h)^2+k but i dont know what to put for h so i put 1

Answer 5

h could be 0 as well and k here would be 3

Answer 6

x-1 denotes you're shifting right to 1 units.

Answer 7

so how would you write it if h is 0

Answer 8

\[\large \bf y=x^2+3\]

Answer 9

ohhh ok if i write the equation for 2 more could you check it?

Answer 10

Sure

Answer 11

8. A square root function was translated 2 left,5 up and was reflected over the x-axis.

Answer 12

i got \[\sqrt{x-2}+5\]

Answer 13

Wrong :(

Answer 14

tbh i dont even know the proper equation for this

Answer 15

First, they asked 2 left, it'd be sqrt(x+2)

Answer 16

And reflection over x-axis, so
\[\large \bf y=-\sqrt{(x+2)}+5\]

Answer 17

ohh ok and then when its not reflected you would take out the negative?

Answer 18

Answer 21

Sure

Answer 22

9. A linear function was translated 3 down and reflected. Give the equation and graph

equation: -3x+1
