Answer:
c) f(x)=3x+1
Step-by-step explanation:
the graph of this function, g(x), is y=3x-1, we know this because the slope is 3 and the y intercept is -1.
finding slope:
subtract the y values and x values and then divide.
y2-y1/x2-x1=2+1/1-0
=3/1
slope=3
finding the y intercept:
more of a visual task, find where the line intersects on the y axis. in this case, it is at -1
plug it in:
next all you have to do is plug this into slope intercept form (y=mx+b), where m is slope and b is y intercept.
y=3x-1
making f(x) from g(x):
all you have to do is add 2 to the y intercept because the question says f(x) is 2 units above g(x).
y=3x-1+2
<em>y=3x+1</em>
hope this helps!
Answer:
Step-by-step explanation:
You have to use the discriminant for this. If the quadratic is
, then
a = -4, b = -3, and c = 7. The formula for finding the discriminant is
which comes from the quadratic formula, but without the square root sign. Filling in:
which simplifies down to
D = 9 + 112 so
D = 121. This is a perfect square, so the solutions will be 2 real. Just so you know, you will NEVER have a solution like the one offered in the third choice down. If you have one imaginary root, you will ALWAYS have a second by the conjugate rule.
