8(5) + 1
40+ 1 = 41
41 is the answer.
Answer:
domain: {x | x is a real number}
range: {y l y> -8}
Step-by-step explanation:
f(x) = 4x² – 8 is a parabola, a U shape.
Since the stretch factor, 4, is positive, it opens up, there it will have a minimum value, the lowest point in the parabola.
y > -8 because the minimum is -8.
Parabolas do not have restricted "x" values. "4" does not restrict x because it is the stretch factor, which determines how wide the parabola is.
Quadratic standard form:
f(x) = ax² + bx + c
"a" represents how wide the graph is. If it's negative it opens down, if it's positive it opens up.
"b", if written, tells you it is not centred on the y-axis. It is not written, so the vertex is on the y-axis.
"c" is the y-intercept. In this case, since b = 0, it is also the minimum value.
Answer: 1 1/3
Step-by-step explanation: 12/3 is 4, so if there are 4 slices remaining (since they ate 2/3 already). Dividing the remaining 4 among them means each person gets 1 1/3 of the remaining 4 slices
Answer:
-2x2a • (2x2 + 4b - 5)
Step-by-step explanation:
Step by step solution :
Step 1 :
Equation at the end of step 1 :
2xa • ((-4xb - 2x3) + 5x)
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
-2x3 - 4xb + 5x = -x • (2x2 + 4b - 5)
Trying to factor a multi variable polynomial :
3.2 Factoring 2x2 + 4b - 5
Try to factor this multi-variable trinomial using trial and error
Factorization fails
Multiplying exponential expressions :
3.3 x1 multiplied by x1 = x(1 + 1) = x2
Final result :
-2x2a • (2x2 + 4b - 5)
