Which of the quadratic functions has the widest graph? a. y = –4x2 b. y = 0.3x2

Step-by-step explanation:

A vertical stretching is the stretching of the graph away from the x-axis.

A vertical compression is the squeezing of the graph towards the x-axis.

A compression is a stretch by a factor less than 1.

For the parent function y = f(x), the vertical stretching or compression of the function is a f(x).

If | a | < 1 (a fraction between 0 and 1), then the graph is compressed vertically by a factor of a units.

If | a | > 1, then the graph is stretched vertically by a factor of a units.

For values of a that are negative, then the vertical compression or vertical stretching of the graph is followed by a reflection across the x-axis.

Thus, the equation with the widest graph is 0.3x^2.

step-by-step explanation:

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
