The graph of an exponential function y = a * 2^x passes through the point (2, 16). What is the value of a? A. 2 B. 4 C. 6 D. 8 相关知识点: 试题来源: 解析 B。将点(2,16)代入函数可得 16 = a * 2^2,解得 a = 4。选项 A、C、D 不符合条件。
用e表示的原因确实不明,但可能因为e是指数函数(exponential)一字的首字母。另一看法则称a,b,c,d有其他经常用途,而e是第一个可用字母。 就像圆周率π和虚数单位i,e是数学中最重要的常数之一。它有几种等价定义,下面列出一部分。 定义e为下列极限值: e=limₙ→∞(1+1/n)ⁿ e=limₜ→₀(1+t)...

integer, we apply a new, deep theorem of Bilu, Hanrot & Voutier and some results on the class number of quadratic field to show that the only positive integer solution of the exponential Diophantine equation a(superscript 2x)+(3a^2-1)(superscript y)=(4a^2-1)(superscript z) is x=y=...
Exponential Equation: We are given an exponential equation {eq}y=c{{a}^{x}} {/eq}. A table that contains some points that satisfy the given exponential equation is also given. Use the given points to obtain the constants {eq}a {/eq} and {eq}c {/eq}....
6. What is true about the exponential function$$ y = 1 0 x - 2 ? $$C a. The possible values for x can be solved based on y-values. b. This can also be considered as an exponential equation. c. This shows the relationship between two variables. d. The possible values for y ...
7. The intercept of the function is the value of y when x is equal to zero. 函数的截距是当x等于零时y的值。 8. The exponential function represents a relationship where the variable x is in the exponent. 指数函数表示了一个变量x在指数中的关系。 9. The logarithmic function represents the ...
