Answer:
See below
Step-by-step explanation:
Question 2:
A relation is a function if every different x-value has a y-value. Since this relation has two outputs for x = 4 (1 and 9), it is NOT a function.
Question 3:
Plug the three points listed (-1, 0, 1) into the function and get their outputs. This will be the range.
f(x) = 2x + 4
Plug in -1.
f(-1) = 2(-1) + 4
f(-1) = -2 + 4
f(-1) = 2
f(x) = 2x + 4
Plug in 0.
f(0) = 2(0) + 4
f(0) = 4
f(x) = 2x + 4
Plug in 1.
f(1) = 2(1) + 4
f(1) = 2 + 4
f(1) = 6
This makes the range {2, 4, 6}.
Um ma is tht even right ❤️
New volume of mixture
= 30%/20%*30 oz
= 45 oz
Jalen must therefore add (45-30)=15 oz of water.
Answer:
A. the number 2 is a root of F(x) = 3x^2 - 11x +10
D. (x-2) is a factor of 3x^2 - 11x +10
E. (3x^2 - 11x + 10) / (x - 2) = (3x - 5)
Step-by-step explanation:
Divide it by -1 to get positive 81
