For f(x)=ax^2+bx+c
the axis of symmetry is -b/2a

f(x)=2x^2+4x+2
a=2
b=4
-4/(2*2)=-4/4=-1

the axis of symmetry is x=-1

B

What is the equation in point-slope form of a line that passes through the points (7, −8) and (−4, 6) ?
Gala2k [10]
(7,-8)(-4,6)
slope = 6 - (-8) / (-4 - 7) = (6 + 8) / -11 = -14/11

point slope : y - y1= m(x - x1)
(-4,6)...x1 = -4 and y1 = 6
now we sub
y - 6 = -14/11(x - (-4) =
y - 6 = -14/11(x + 4) <===

Find the percent of error if the estimate is $230 and the actual amount is $245. round to the nearest whole percent.
qwelly [4]

Percentage error = 245-230/245 * 100 = 15/245 * 100 = 6.12%

After rounding off, it would be 6%
