Which graph represents a function? On a coordinate plane, a straight vertical line crosses the y-axis 0 times and the x-axis 1 time.

On a coordinate plane, a curved line crosses the y-axis 2 times and the x-axis 1 time.

On a coordinate plane, 2 curved lines are shown. Both lines touch the y-axis 1 time and the x-axis 1 time.

On a coordinate plane, a straight horizontal line crosses the y-axis 1 time and the x-axis 0 times.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
