Beginning with the quadratic equation y = ax2 + bx + c, Fred calculated
and then plugged that number in for
x to get a y. What is ONE reason he might have done this?
to find the vertex
to find the x-intercept
to find the y-intercept
to find the width of the parabola

If you answer right ill give brainliest, : )

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
