Answer:
Option A. (4,0) and (-1,0)
Step-by-step explanation:
we know that
The equation of a vertical parabola in factored form is equal to

where
a is a coefficient
x_1 and x_2 are the zeros or x-intercepts of the function
In this problem we have

we have

The leading coefficient is negative, that means the parabola open downward
The zeros of the function are

Remember that the x-intercepts are the values of x when the value of the function is equal to zero
therefore
The x-intercepts are (4,0) and (-1,0)
Answer:
Step-by-step explanation:
Because 3x10=30 and 31 is greater than 30 by 1 more.
I believe the value of x would be 20.
Answer:
-9a+12
Step-by-step explanation:
Answer: Second option, 2^2x+6=2^6
Step-by-step explanation:
You can simplify 4^x+3 by making the 4 into 2^2. By doing this you also multiply the current powers of 4 by 2, giving you (x+3) • 2, furthermore, 2^2x+6.
64 is a power of 2, so just multiply 2 by itself until you get the number you’re looking for and count how many times you do it. Or just type each option, like 2^4, 2^6 into the calculator until you find it.
