Pls help its not that hard, im in 7th grade

Y=4x^2+x-1 solve using quadratic formula

Which of the following describes the graph of y--4x-36 compared to the parent square root function? stretched by a factor of 2, reflected over the x-axis, and translated 9 units right stretched by a factor of 2, reflected over the x-axis, and translated 9 units left stretched by a factor of 2, reflected over the y-axis, and translated 9 units right stretched by a factor of 2, reflected over the y-axis, and translated 9 units left save and exit next submit

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2
