That equation cannot be solved since there are 2 unknown in the equation (x and y) but only 1 equation. The number of unknowns must be equal to the number of equations (for simultaneous equations)
y=4x2+3x+8
No.
First you need to solve for y. So write 4x2+y=16 so y=16-4x2 Now write f(x)=16-4x2
y = 2 (4X2=8) +9 = 17
The equation y = 4x^2 + 5 is a parabola
It is a parabola with its vertex at the origin and the arms going upwards.
They are expressions.
x = 0 and y = 4
y=-10x-4
Y = 4x2 + 6x - 1Use the pq-formula:x = -4/2 +- sqrt ((4/2)2 -(-1))x = -2 +- sqrt((16/4) +1)x = -2 +- sqrt(4 +1)x1 = -2 + sqrt(5)x2 = -2 - sqrt(5)
x = y = 0 ?
symmetric property
