Answer:
Graphs behave differently at various x-inter cepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.
Suppose, for example, we graph the function. f(x) = (x+3)(x - 2)²(x+1)³.
Notice in the figure below that the behavior of the function at each of the x-intercepts is different.
Answer:
x=4/9, one solution
Step-by-step explanation:
Given: 2x+7x=4
Combine like terms: 9x=4
Divide by 9 on both sides to isolate the variable x: x=4/9
Answer:
( -3√5)
Step-by-step explanation:
√45 - √20 - 4√5 = √5*3*3 - √2*2*5 - 4√5
= 3√5 - 2√5 - 4√5
= √5 (3 - 2 - 4)
= ( -3√5)
Answer:
<u>Step-by-step explanation:</u>
Inverse is when you swap the x's and y's and then manipulate the equation to solve for y.
