Just plug in 2 for x since f(x) = f(2)
f(2)=2^2+1
f(2)=4+1
f(2)=5
Answer:
the answer is 7x + 437
Step-by-step explanation:
1) 7 is the only number with a variable, <em>x</em>, so it will remain as it is.
2) -4+4= 0
3)1+1= 2
4) 2+435= 437
7) combine 7x and 437 together. 7x + 437.
We cant go any further, because 7x and 437 are not liketerms.
Answer:
(B). between 2.5 and 3.0 and between 4.0 and 4.5.
Step-by-step explanation:
According to the Question,
- If the value of the function is 0 at x=c, then c is a root or zero of the function. It means the graph of function intersects the x-axis at its zeroes.
From the given table it is clear that the value of function are
x | f(x) | Sign
2.0 | 2.8 | Positive
2.5 | 1.1 | Positive
3.0 | –0.8 | Negative
3.5 | –1.2 | Negative
4.0 | –0.3 | Negative
4.5 | 0.7 | Positive
- The sign of values of function changes in interval 2.5-3.0 and 4.0-4.5. It means the graph of function must intersect the x-axis in intervals 2.5-3.0 and 4.0-4.5. So, the zeros of the function lie between 2.5 and 3.0 and between 4.0 and 4.5.
Therefore, the correct option is B.
