(x - h)^2 = 4p(y - k)
(-1 - 3)^2 = 4p(8 - 0.5)
(-4)^2 = 4p(7.5)
16 = 30p
p = 16/30
p = 8/15
(x - 3)^2 = 16/15(y - 0.5)
15(x^2 - 6x + 9) = 16y - 8
15x^2 - 90x + 135 = 16y - 8
16y = 15x^2 - 90x + 135 + 8
y = 15/16 x^2 - 90/16 x + 143/16
f(x) = 15/16 x^2 - 90/16x + 143/16
Y=3x please mark as brainliest:)
Answer:
Step-by-step explanation:
Slope-intercept from: y = mx +c
Here, m is the slope & c is the y-intercept.
So, we have to isolate y. To isolate y first subtract 2x from both sides.
2x - 3y = -9
-3y = -2x -9
Now, divide the entire equation by the co efficient of y (-3)
Answer:
f(x) = -2x +9
Step-by-step explanation:
We can use the slope intercept form
y= mx +b where m is the slope and b is the y intercept
y = -2x +9
Replacing y with f(x)
f(x) = -2x +9
