Given the function f described by fly)=9y2 + 7y-6, find the function values.
f(-5) = 0
(Simplify your answer. Type an integer or a fraction.)
Answer:
f(- 5) = 184
Step-by-step explanation:
Substitute y = - 5 into f(y) , that is
f(- 5) = 9(- 5)² + 7(- 5) - 6
= 9(25) - 35 - 6
= 225 - 41
= 184

Write an equation in slope intercept form for the graph of the line.
Answer:
y = 2x - 3Step-by-step explanation:
Slope intercept form:
y = mx + b, where m - slope, b - y-interceptTake two points from the graph:
(2, 1) and (3, 3)Find the slope:
m = (3 - 1)/(3 - 1) = 2/1 = 2Find the y-intercept using point (2, 1) and the equation above:
1 = 2*2 + bb = 1 - 4b = -3The line is:
y = 2x - 3Answer:
Y = 2x - 3 or Y = 8/3x - 3
Step-by-step explanation:
Y = mx + b
we have a y intercept of -3 since the graph crosses the y axis only at -3 and it heads to y = 3 starting from the y intercept.
and thus we are 5 units away from 3 which is m = a/c = 8/3
m = 8/3
y = 8/3x - 3
it's either this or we'll simply plot the final and initial positions of x and y respectiveky. so m = 3-1/3-2 = 2/1 = 2
and so the equation would turn out to be -
y = 2x -3

Answer:
A = 192
Step-by-step explanation:
r = 16/2 = 8
A = 3x(8)^2
8^2 = 64
A = 3 x 64 = 192
Radius is half the diameter.
The diameter is shown as 16, so the radius would be 16/2 = 8 in.
Area = 3 x 8^2
Area = 3 x 64
Area = 192 square inches

I've attached a graph to show why these two are true. Remember that in an absolute value function, the result is always positive. However, because there's a negative constant multiplying the absolute value function, this flips the graph over the x-axis and the result is now always negative. In other words, no matter how big or small x is, y will always get smaller.
How do u slove this for y intercept?
(4, 1); slope=3/2
Answer:
y-intercept=-5
Step-by-step explanation:
y=mx+b m/slope=3/2 the point is (x,y)/(4,1)
1=3/2(4)+b
1=12/2+b
1=6+b
-6-6
-5=b

What is the range of the relation?
Question 9 options:
{–4, –2,–1, 2}
{–4, 4}
{–3, –2, 0, 2}
{–4, –2, –1, 0, –2}
Step-by-step explanation:
the range of a relation or function is the interval or set of valid result values (y values).
in contrast to the domain, which is the interval or set of valid x values.
so, as y values we have here
-3, -2, 0, 2
so, the third answer option is correct.
