Answer:
A = 9, B = 5, C = 3
the parabola opens upwards
y-intercept = 3
Step-by-step explanation:
Since the equation is f(x)=9x^2+5x+3, you can determine what a, b, and c are by associating it with a quadratics standard form, <u>ax^2+bx+c</u>. The numbers correspond with each letter in the skeletal equation.
To determine whether the parabola opens up or down, you can simply look at the a value. If <u>x > 0</u>, the the parabola will <u>open upwards</u>, whereas if <u>x < 0</u>, the parabola will <u>open downwards</u>.
To determine <u>y-intercept</u>, just plug in the value of 0 into x and solve for y.
Answer:
Any equation with the slope -3 and a y intercept that does not equal 5
Step-by-step explanation:
a line is parallel if the line have the same slope, and different y intercepts
3x+y=5
in slope intercept form is
y=-3x+5
slope : -3
y intercept 5
