Answer:
B
Step-by-step explanation:
f(x) is just another way of saying y, so this function is really y=4x-5. So if you do y+3 then the y intercept will increase by 3 shifting the graph up 3 units.
x^2+3x-18 in factored form leaves us the two factors of;
(x+6)(x-3)
So from your choices (x-3) is the answer
I don't understand can you show have to do this pleas
Answer:
c. x+4
Step-by-step explanation:
A graph shows zeros to be -2, 1, 3, 4. This means the factors will be ...
(x +2)(x -1)(x -3)(x -4)
The factor (x+4) is not among the factors of the given expression.
To help solve this, we need to use the slope formula.
(y2 - y1) / (x2 - x1). We get these values by picking two points on a line.
For JL, we will pick points (-5, -3) and (-2, -4).
y1 = -4
y2 = -3
x1 = -2
x2 = -5.
Let's plug these into our formula.
(-3) - (-4) / (-5) - (-2) = -1/3
For LN, we will pick points (-2, -4) and (7, -7).
y1 = -7
y2 = -4
x1 = 7
x2 = -2.
Lets plug these values into our equation.
(-4) - (-7) / (-2) - (7) = -1/3
Therefore,
(-3) - (-4) / (-5) - (-2) = (-4) - (-7) / (-2) - (7)
The correct answer is G.
